Answer: 18.1%

Explanation:

The percent yield for a reaction whose theoretical yield is 42.0 g and actual yield is 7.6 g is 18.09 g.

Percentage yield can be calculated by dividing the actual yield by the theoretical yield multiplied by 100.

The theoretical yield is 42.0 g

The actual yield is 7.6 g

\(\dfrac{actual\;yield}{theoretical \;yield} \times 100\\\\\\\dfrac{7.6}{42.0} \times 100 = 18.09\)

Thus, the percentage yield is 18.09 g.

Answer:

For much of the past century, scientists studying drugs and drug use labored in the shadows of powerful myths and misconceptions about the nature of addiction. When scientists began to study addictive behavior in the 1930s, people with an addiction were thought to be morally flawed and lacking in willpower. Those views shaped society’s responses to drug use, treating it as a moral failing rather than a health problem, which led to an emphasis on punishment rather than prevention and treatment.

Today, thanks to science, our views and our responses to addiction and the broader spectrum of substance use disorders have changed dramatically. Groundbreaking discoveries about the brain have revolutionized our understanding of compulsive drug use, enabling us to respond effectively to the problem.

As a result of scientific research, we know that addiction is a medical disorder that affects the brain and changes behavior. We have identified many of the biological and environmental risk factors and are beginning to search for the genetic variations that contribute to the development and progression of the disorder. Scientists use this knowledge to develop effective prevention and treatment approaches that reduce the toll drug use takes on individuals, families, and communities.

Despite these advances, we still do not fully understand why some people develop an addiction to drugs or how drugs change the brain to foster compulsive drug use. This booklet aims to fill that knowledge gap by providing scientific information about the disorder of drug addiction, including the many harmful consequences of drug use and the basic approaches that have been developed to prevent and treat substance use disorders.

At the National Institute on Drug Abuse (NIDA), we believe that increased understanding of the basics of addiction will empower people to make informed choices in their own lives, adopt science-based policies and programs that reduce drug use and addiction in their communities, and support scientific research that improves the Nation’s well-being.

D

Explanation:

Answer:

Pressure

Explanation:

Answer:

The solubility of a gas in a liquid would be increased by an increase in its pressure. Thus, Option D is correct.

Explanation:

According to Henry's law: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

Thus, as the pressure increases the solubility will also increase.

A methane molecule (CH4) is considered symmetrical because it possesses a symmetric structure and exhibits symmetry operations.

Symmetry refers to a balanced arrangement of elements that can be divided into equal parts by a plane, axis, or center. In the case of methane, it exhibits several symmetrical characteristics.

Firstly, methane has a tetrahedral molecular geometry, with the carbon atom at the center and four hydrogen atoms positioned around it. This geometry ensures that the molecule is symmetrical in terms of its spatial arrangement.

Each hydrogen atom is located at one of the vertices of the tetrahedron, forming equal angles and distances with respect to the central carbon atom. This symmetry is maintained regardless of the orientation of the molecule.

Additionally, methane possesses rotational symmetry. It can be rotated around any of the carbon-hydrogen bonds, and the molecule will retain its overall appearance.

The symmetry of methane arises from its molecular structure and the equal distribution of electron density around the central carbon atom. The four hydrogen atoms are bonded to the carbon through sigma bonds, which have a cylindrical symmetry. This balanced arrangement of the atoms contributes to the overall symmetry of the molecule.

Answer:

Explanation:

I am almost sure that the products are identical.

If you increase the pressure of the reaction 2A(g) + B(g)C(g) + 2D(g)the reaction will shift forward to the side with little moles of gas.

Le Chatelier's principle states that if pressure is raised, the reaction will favor the direction with a lower number of gas moles.

On this  case, the cleared out side includes a add up to of three gas moles (two moles of A and one mole of B), whereas the correct side covers four gas moles (one mole of C and two moles of D). In this way, the balance will move towards the left-hand side in arrange to diminish the collective gas particles and relieve the rise in weight. The levels of A and B will rise, as the levels of C and D will decrease.

Answer:

2 Fe(HCO₃)₃ + 3 CaO ---> 1 Fe₂O₃ + 3 Ca(HCO₃)₂

Explanation:

The unbalanced equation:

Fe(HCO₃)₃ + CaO ---> Fe₂O₃ + Ca(HCO₃)₂

Reactants: 1 iron, 3 hydrogen, 3 carbon, 10 oxygen, 1 calcium

Products: 2 iron, 2 hydrogen, 2 carbon, 9 oxygen, 1 calcium

As you can see, the reaction is clearly unbalanced because the number of each element on both sides is different. The best way to go about balancing an equation is by trying to first balance an element located in only one molecule on either side. For example, I started trying to balance  iron. After balancing iron, I looked to balance other elements that would have been affected by the new coefficient (i.e., hydrogen, carbon).

The balanced equation:

2 Fe(HCO₃)₃ + 3 CaO ---> 1 Fe₂O₃ + 3 Ca(HCO₃)₂

Reactants: 2 iron, 6 hydrogen, 6 carbon, 21 oxygen, 3 calcium

Products: 2 iron, 6 hydrogen, 6 carbon, 21 oxygen, 3 calcium

Now, with these coefficients, the quantity of each element on both sides is the same.

The property X is an extrinsic property.

The term extensive property refers to the type of property that depends on the amount of the substance present. We must recall that an intensive property does not in any way depend on the number or the amount of the substance present in the sample.

If we have a good look at the table that is being referred to here, we would see that the mass of the substance tends to increase as a certain un named property of the substance X is increasing. This implies that the property X is affected by the mass of the object which is the quantity of matter in the object. This gives us an idea that the property that we are referring to can not be an intrinsic  property since it varies with the mass of the substance that is under study as shown.

We can then conclude that the property X is an extrinsic property.

What happens to an organism if an organ or organ system does not function properly?

All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.

Why do organisms forget some things and remember others?

The main reason is that in order for us to store information and remember it, our senses have to capture them perfectly.

How are some organisms able to survive as single cells while other types of organisms have multiple body systems each made of many cells?

The one cell can do it all.

Why do some animals have a heightened sense such as sight or smell?

All aspects of an animal's senses, from the structure of its sensory organs to the numbers of receptor cells and the behaviour of its brain, are ultimately derived from its genes. It's the genes that decide how well an animal can smell, see, hear or taste.

Do organisms instinctively know how to respond to the environment, or do they have to learn how to respond?

All animals, including humans, have instinctual behavior, but animals can't survive on their instincts alone. Animals need to be able to respond to their environment to survive. ... This process of modifying behavior based on experience is called learning.

The mass of 0.550 mol of methanol, CH3OH, is 17.6 g

To find the mass of 0.550 mol of methanol, CH3OH, we need to use the molar mass of CH3OH. The molar mass is the sum of the atomic masses of each element in the molecule, which can be found on the periodic table.
For CH3OH, we have:

- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.01 g/mol (there are 4 hydrogen atoms in CH3OH)
- Oxygen (O): 16.00 g/mol

So the molar mass of CH3OH is:

12.01 g/mol + (1.01 g/mol x 4) + 16.00 g/mol = 32.04 g/mol

This means that one mole of CH3OH weighs 32.04 grams.

To find the mass of 0.550 mol of CH3OH, we can use the following formula:

mass = number of moles x molar mass

So the mass of 0.550 mol of CH3OH is:

0.550 mol x 32.04 g/mol = 17.62 g

Rounding this to three significant figures gives us:
17.6 g

Therefore, the mass of 0.550 mol of methanol, CH3OH, is 17.6 g (rounded to three significant figures).
