Answer: Weathering

Explanation:

Weathering can break down rocks and change it shapes.

To supply oxygen to the body, the respiratory system works closely with the circulatory system. As oxygen is taken in into the lungs, it travels through blood vessels, which then circulate oxygen-rich blood to cells and tissues.

The number of electrons can be predicted in a neutral atom  because the number of protons and electrons in a neutral atom will be identical, we can readily calculate the electron number from the atomic number.

An atom's atomic number can be used to forecast its electrical structure. The atomic number can be used to forecast the total number of electrons because neutral atoms have an equal number of protons and electrons.

So, If you know what group the atom's element belongs to and the group number correlates to the number of electrons on the valence shell and you can determine how many atoms are on the atom's valence shell.

In a reaction involving sodium metal and chlorine gas, the amount of sodium metal required to react with 0.950 grams of chlorine gas would be 0.62 grams

From the balanced equation of the reaction:

2Na (s) + Cl2 (g) ---------> 2NaCl (s)

The mole ratio of Na to Cl2 is 2:1.

Mole of 0.950 grams of chlorine gas = 0.950/70.906

                                                             = 0.0134 moles

Equivalent mole of Na = 0.0134 x 2 = 0.0268 moles

Mass of 0.0268 moles Na = 0.0268 x 22.99

                                           = 0.62 grams

That oil sands executive is greedy and heartless and therefore can't be trusted when she claims is Ad hominem attack. So, Option B is correct.

4-  The argument in question 4 is an example of an ad hominem attack. This is due to the argument's focus on the character of the oil sands executuive rather than the actual problem, which is how to improve the company's environmental record.

The argument holds that the executive cannot be believed when she says she wants to improve the company's environmental record because she is avaricious and callous. This is an error in logic, though, as the executive's character may not necessarily be related to the company's environmental policies.

5-  The argument in question 5 is an example of an appeal to ignorance. This is because the argument states that there is no proof that humans are causing climate change, so it must be natural causes. Just because there is no conclusive proof that humans are causing climate change, it does not mean that they are not.

The argument assumes that just because there is no evidence to the contrary, the argument must be true. This is a logical fallacy.

Answer:

This question lacks options, the options are:

A: Two students of similar mass run into each other. They bounce off each other when they collide.

B: Two students of similar mass run side by side into a wall and punch holes of equal size before emerging on the other side.

C: Two students of similar mass run in opposite directions, but one accelerates at twice the rate of the other.

D: Two students of similar mass run at the same speed in opposite directions on a track. They will collide with 400 Newtons of force in 400 meters.

The answer is A.

Explanation:

Isaac Newton proposed three laws, which he called laws of motion. The third of these laws states that for every action, there is an equal and opposite reaction. This means that if an object A collides with object B, object B will exert a force of similar magnitude but in opposite direction on object A.

From the examples in the option, when two students of similar mass run into each other. They bounce off each other when they collide. This means that student 1 and student 2 will go in opposite directions after collision with one another. This portrays Newton's third law of motion.

Taking into account the reaction stoichiometry, the mass of ammonia formed is 34 grams.

The process in the petroleum industry involves bringing oil and gas to the surface, converting crude oil into other products, and selling those products to customers. The correct choice is B. upstream; downstream.

In the petroleum industry, the process can be divided into three main sectors: upstream, midstream, and downstream. Upstream activities involve the exploration and extraction of crude oil and natural gas from underground reserves. This includes locating oil and gas deposits, drilling wells, and bringing the oil and gas to the surface.

Once the oil and gas are extracted, the midstream sector comes into play. Midstream activities involve the transportation, storage, and processing of the crude oil and natural gas. This includes pipelines, storage tanks, and facilities that separate the oil and gas into different components.

Finally, the downstream sector involves refining the crude oil into various products and selling those products to end consumers. Downstream activities include refining, petrochemical production, distribution, and marketing of the final petroleum products, such as gasoline, diesel, jet fuel, lubricants, and various other chemicals.

Therefore, in the given scenario, the correct choice is B. upstream; downstream, as it represents the process of bringing oil and gas to the surface (upstream) and then converting crude oil into other products and selling them to customers (downstream).

The volume of Object 2 can be determined from the water displacement data by subtracting the initial volume of the water (120.0 mL) from the final volume after the sphere is added (135.8 mL). This gives us a difference of 15.8 mL, which is the volume of Object 2.

The chemical explanation for this procedure is that the volume of Object 2 is calculated by subtracting the initial volume of water from the final volume of water after the object is added. This is due to the fact that the volume of the object displaces the water, and so the amount of water displaced is equal to the volume of the object.

Answer:

Rainwater is considered soft water because it is naturally low in mineral content - specifically calcium and magnesium ions - which are the ions that make water hard. As rainwater falls, it does not come into contact with the ground or rocks long enough to pick up significant amounts of these ions. Therefore, it retains its softness. However, as rainwater flows on the ground, it can collect minerals that can make it harder.

The given values are as follows; Nitrous acid = HNO2 = 0.253 mMolar concentration of KNO2 = 0.111 m.Ka (dissociation constant of HNO2) = 4.50 x 10^-4.The ionization reaction of nitrous acid in an aqueous solution is represented as;HNO2 + H2O ⇋ H3O+ + NO2-From the above equation, we see that one H+ ion is produced per molecule of HNO2 that dissociates.

Nitrous acid is a weak acid, so we can assume that it is partially ionized in the solution. To find out the pH of the given solution, we need to first calculate the concentration of H+.Concentration of HNO2 = 0.253 MConcentration of KNO2 = 0.111 MHence, the total concentration of nitrite ions = 0.111 MTo calculate the concentration of nitrous acid, we use the following formula;0.253 M – x = x0.253 = 2xThus, the concentration of nitrous acid = 0.126 M.Next, we calculate the concentration of H+ using the ionization constant of nitrous acid as shown below;Ka = [H+][NO2-]/[HNO2]4.50 x 10^-4 = [H+] [0.111] / [0.126][H+] = 4.50 x 10^-4 * 0.126 / 0.111[H+] = 5.10 x 10^-4Now, the pH can be calculated by taking the negative logarithm of the concentration of H+.Hence,pH = -log[H+]= -log(5.10 x 10^-4) pH = 3.29Therefore, the pH of the given solution is 3.29.

To know what each letters represents, we must understand what an energy profile diagram is.

An energy profile diagram is a representation of chemical reaction, showing the pathways in which reactants follows to become products.

With the above information, we can say that:

Every reaction has a peak energy. This peak energy is referred to as the activation complex. The activation complex is the highest energy of the reaction. Looking at the diagram, we can see that B is at the peak.

Thus, letter B represents the activation complex

Also, every reaction has activation energy. This is the minimum energy required for a reaction to occur. In profile diagram the activation energy is the energy between the peak (i.e activation complex) and the reactant. from the graph, we can see that letter D lies between the letter B and A.

Thus, we can say letter D is the activation energy
