If you get a root canal or any other potentially painful procedure done at the dentist's office, he or she will probably inject your gums with a local anesthetic to "numb the pain." Neurons that trigger pain are called nociceptors. They trigger pain in order to alert the body to potentially dangerous stimuli. Most local anesthetics hinder the activity of all local neurons, not just nociceptors, so pain is not the only sensation that goes away temporarily. Because all feeling is gone, you can end up drooling on yourself without knowing it.

Considering this information about local anesthestics, which of the following statements best demonstrates that science is an ongoing process that changes in response to new information and discoveries?
A. There are a variety of local anesthetics being used today, including lidocaine, prilocaine, and mepivacaine.
B. Sir Charles Sherrington, who discovered nociceptors, wrote a book about the nervous system that helped show its role in allowing organisms to adapt to their environments.

how to find molecular mass of ammonia.

Please give proper answers only, inappropriate answers will be reported, the best ones will be marked as brainliest.​

Answers

Answer:

17.03052 g/mol

Explanation:

Ammonia formula is given as NH3.

To estimate the molar mass of any compound, we have to add up the molar masses of every atom of the given compound. Ammonia comprises of one nitrogen atom and three hydrogen atoms.

So the molar mass of ammonia is

N: 14.0067 g/mol

H: 1.00794 g/mol

The molar mass of ammonia will thus be

14.0067 g/mol +3× 1.00794 g/mol =17.03052 g/mol

If an atmosphere consisting of an ideal gas were indeed homogeneous (constant density) all the way to the top at z = H, find the temperature at that top. Could such an atmosphere actually exist, even in principle? Why or why not?

Answers

The temperature at the top of an atmosphere consisting of an ideal gas with constant density can be found using the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.


Assuming the density of the gas is constant throughout the atmosphere, we can express the pressure as P = ρgh, where ρ is the density, g is the acceleration due to gravity, and h is the height.

Since the atmosphere is homogeneous, the pressure at the top (P_top) is the same as the pressure at the bottom (P_bottom), so we have P_top = P_bottom = ρgh.

Using the ideal gas law, we can write ρghV = nRT, where V is the volume of the gas.

Assuming the volume of the gas is constant, we can cancel out V, and rearranging the equation, we get T_top = (nRT_bottom)/(nR) = T_bottom.

Therefore, the temperature at the top of the atmosphere would be the same as the temperature at the bottom.

In practice, however, it is not possible for an atmosphere to have constant density all the way to the top. As we go higher in the atmosphere, the density decreases due to decreasing pressure and temperature. This is because gravity becomes weaker at higher altitudes. Therefore, in reality, the temperature would decrease as we move higher in the atmosphere.

So, while a homogeneous atmosphere with constant density all the way to the top cannot exist in practice, it can be considered as an idealized scenario for understanding certain aspects of atmospheric behavior.

why should cleaning supplies be stored away from food

Answers

Cleaning supplies should be stored away from food for several important reasons:

1. Contamination: Cleaning supplies often contain chemicals that can be harmful if ingested. If they come into contact with food, they can contaminate it and pose a risk to human health. Some common cleaning agents, such as bleach, ammonia, and disinfectants, can cause nausea, vomiting, diarrhea, or more serious health issues if consumed.

2. Chemical reactions: Certain cleaning products can undergo chemical reactions when they come into contact with certain food items. For example, mixing bleach and acidic foods or liquids (such as vinegar, citrus fruits, or juices) can create toxic chlorine gas. Storing cleaning supplies near food increases the risk of accidental mixing or spillage, leading to dangerous chemical reactions.

3. Packaging mix-ups: Cleaning supplies and food items often come in similar packaging, such as spray bottles or containers. Placing them in close proximity increases the chances of mistakenly using the wrong product. Consuming cleaning products can be extremely hazardous and cause severe harm or even death.

4. Cross-contamination: Even if the cleaning supplies don't directly contact the food, there is still a risk of cross-contamination. Residual chemicals or fumes from the cleaning supplies can migrate to nearby food items, compromising their safety and quality.

To ensure food safety, it is crucial to store cleaning supplies in a separate, designated area away from food storage areas, preferably in a locked cabinet or a well-ventilated storage space. It's important to read and follow the instructions on cleaning product labels, use them as intended, and keep them out of reach of children and pets.

The balanced chemical equation for the reaction of calcium chloride (CaCl₂) with a fatty acid (R-COOH) to form soap (R-COONa) and carbon dioxide (CO₂) is:

CaCl₂ + 2 R-COOH → R-COONa + CO₂ + 2 HCl

In this reaction, calcium chloride (CaCl₂) reacts with a fatty acid (R-COOH), which is the structure of a typical soap molecule, to form soap (R-COONa) and carbon dioxide (CO₂) as products. The balanced equation is obtained by ensuring that the number of atoms of each element is the same on both sides of the equation.

To balance the equation, the coefficients of the reactants and products are adjusted. In this case, two molecules of the fatty acid are required to react with one molecule of calcium chloride to form two molecules of soap, one molecule of carbon dioxide, and two molecules of hydrochloric acid (HCl) as a byproduct.

explain how comparative anatomy supports the theory of natural selection and evolution.

Answers

Comparative anatomy is the study of similarities and differences between the body structures of different species. The study of comparative anatomy supports the theory of natural selection and evolution.

Here's how:How comparative anatomy supports the theory of natural selection and evolution?Charles Darwin, the father of the theory of evolution, recognized that different species share common anatomical features, such as a similar bone structure. He hypothesized that if a species could use the same bone structure to perform different functions, the bone structure could be adapted over time to perform these new functions better.

This was a radical idea at the time because most scientists believed that species were created separately. However, Darwin's ideas were supported by the study of comparative anatomy, which showed that many species share similar structures, indicating that they share a common ancestor. Comparative anatomy also shows that species have adapted over time to perform new functions as they evolved.Comparative anatomy has also helped scientists understand the evolutionary history of different species. By comparing the structures of different species, scientists can identify which structures evolved first and how they evolved over time. This helps scientists create a timeline of how different species have evolved over millions of years.Comparative anatomy is just one of many pieces of evidence that supports the theory of natural selection and evolution. However, it is an important piece of evidence because it shows that different species share a common ancestry and have adapted over time to better survive in their environment.

Answers

The object with the greatest gravitational pull is the Earth (option D).

What is gravitational pull?

Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass. It is believed to be mediated by gravitons.

Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

The force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

According to this question, Earth has the highest mass among the listed objects, hence, in accordance to the law of universal gravitation, Earth will possess the greatest gravitational pull.

Calculate the volume of oxygen that was in excess. if 150cm³ of carbon(11) oxide burns in 80cm³of oxygen according to the following equation 2CO + O2 =2CO.​

Answers

If 150cm³ of carbon(11) oxide burns in 80cm³of oxygen according to the given equation the volume of oxygen that was in excess is 5.6 cm³.

From the balanced equation, we can see that 2 moles of CO react with 1 mole of O2. Therefore, we need to determine how much O2 is required to react with 150 cm³ of CO.

Let's start by calculating the number of moles of CO:

n(CO) = V(CO) / molar volume at STP

= 150 cm³ / 22.4 L/mol

= 0.006696 mol

Since the stoichiometric ratio of equation of CO to O2 is 2:1, we need half as many moles of O2 as CO. Therefore, the number of moles of O2 required is:

n(O2) = 1/2 * n(CO)

= 1/2 * 0.006696 mol

= 0.003348 mol

Now we can calculate the volume of oxygen required using the ideal gas law:

PV = nRT

Assuming the temperature and pressure are constant, we can simplify this to:

V = n(RT/P)

where V is the volume of gas in liters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure in atmospheres.

At STP, the temperature is 273 K and the pressure is 1 atm. Therefore:

V(O2) = n(O2)(RT/P)

= 0.003348 mol * (0.0821 L·atm/mol·K * 273 K / 1 atm)

= 0.0744 L

= 74.4 cm³

So the volume of oxygen required to react with 150 cm³ of CO is 74.4 cm³. Since the initial volume of O2 was 80 cm³, the volume of O2 in excess is:

V(excess) = V(initial) - V(required)

= 80 cm³ - 74.4 cm³

= 5.6 cm³

Therefore, the volume of oxygen that was in excess is 5.6 cm³.

Answers

The mass of CuSO₄.5H₂O that is required to prepare 100 mL of a 0.500 mol/L aqueous solution is 84.3045g.

We know that  0.5-mol/L solution of copper(II) sulfate contains 0.5000 moles of copper(II) sulfate, the solute, for every  

1 L= 10³ml of the solution.

This means that the  sample of copper sulfate must contain,

      = (100ml)x0.5 moles of CuSO₄/10³ml

      =   0.05 moles of CuSO₄.

It should be noted that every mole of copper(II) sulfate pentahydrate contains 1 mole of anhydrous copper(II) sulfate, CuSO4, and 5 moles of water of hydration, H₂O.

This means that in order to deliver 0.05000 moles of anhydrous copper(II) sulfate to the solution, we must deliver 0.05000 moles of copper(II) sulfate pentahydrate.

In addition to the 0.05000 moles of anhydrous copper(II) sulfate, this sample will contain,

= 0.5 moles of CuSO₄.5H₂Ox 5 moles of H2O/1mole of CuSO₄.5H₂O.

= 0.25 moles of H₂O.

Therefore, the total mass of the copper(II) sulfate pentahydrate will be equal to the mass of  

0.5 moles of anhydrous copper(II) sulfate and a mass of  0.25moles of water of hydration.

Then, the total mass of the copper(II) sulfate pentahydrate will be equal to the mass of  

0.5000 moles of anhydrous copper(II) sulfate and the mass of  0.25 moles of water of hydration which is given by,

Mass of CuSO₄ = 0.5x159.609=79.8045g

Mass of 5 moles of H₂O =0.25x18.015 = 4.5 g.

Therefore, the total mass of the copper(II) sulfate pentahydrate that will deliver  

0.5 moles of anhydrous copper(II) sulfate to your solution will be,

79.8045+4.5 = 84.3045g

Therefore, the mass of copper(II) sulfate pentahydrate required to make 100 mL of a 0.500 mol/L aqueous solution is 84.3045g

The price of a single icecream cone is $4 plus the price of sprinkles, s.Which equation represents the situation? Joel has some polarizing filters. He knows that the filters absorb some of the light that strikes them, and the light that passes through is polarized in one direction.Joel then passes a beam of light through two filters. He finds that by twisting onewith relation to the other, he can reduce the amount of light. At one point, thesecond filter completely absorbs the light that passes through the first filter. Whichtwo filter angles does he use? What is the effect he sees?____________________________________________________________________________________________________.2. Joel leaves the two filters as they were in Question 10. He then puts a third filterbetween the first two. Explain what he sees when the third filter is at 45.____________________________________________________________________________________________________. the this keyword cannot be used to make it possible for one overloaded constructor to call another overloaded constructor in the same class.
