How would the equilibrium change if NO2 were added to SO2(g) + NO2(g) NO(g) + SO3(g) + heat?A. The equilibrium constant would increase.
B. The amount of NO and SO3 would decrease.
C. The amount of NO and SO3 would increase.
D. The amount of NO2 and SO2 would increase.

Answers

The answer to this question would be that the amount of No and SO3 would increase. The correct choice is C. 

The equilibrium of this chemical reaction would change if NO₂ were added because: C. the amount of NO and SO₃ would increase.

What is an equilibrium?

An equilibrium can be defined as a condition in which there is no net change in the amounts of both reactants and products with respect to time, during a reversible chemical reaction.

This ultimately implies that, the rate of the forwardchemical reaction is equal to the rate of the backwardchemical reaction at equilibrium.

In this context, we can infer and logically conclude that the equilibrium of this chemical reaction would change when NO₂ is added because the amount of NO and SO₃ would increase:

                      SO₂(g) + NO₂(g) ⇆ NO(g) + SO₃(g) + heat

A compound contain only carbon, Hydrogen, Oxygen. Mass percentage of carbon is 52.2%, relative molecular mass of compound is 46, Find how many hydrogen atom present​

Answers

Answer:

Six

Explanation:

Mᵣ                           =  46

Aᵣ(C) = 0.522 × 46 =  24

Difference              =  22

Less 1 O                  = -16

Aᵣ(H)                        =   6

The relative atomic mass of the H atoms is 6.

The molecule contains six hydrogen atoms.

Which refers to a mixture that contains more than one phase in which the characteristics of the particles vary throughout the mixture?

Answers

This type of mixture is a heterogeneous mixture. It is any mixture that is not uniform. Heterogeneous mixtures always have more than one phase.It is made up of substances which stays physically separate with each other. Best example is a mixture of sand and sugar. If you get two samples from different points of the mixture and analyze it, you will see that the concentrations of the components are different and that the two solid phases never combine with each other.

Answer:

C. Heterogeneous

A solution with a pH of 8.0 isa. acidic.
b. neutral.
c. weakly basic.
d. strongly basic.

Answers

A solution with a pH of 8.0 is weakly basic. Thus ,the correct option is C.

The pH scale gives the measure of the acidity or basicity of a solution. It ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions which have a pH less than 7 are acidic, while solutions which have  a pH greater than 7 are basic.

In this case, since the pH is 8.0, which is greater than 7, the solution is basic. However, it is important to note that the basicity of the solution is weak, as it is only slightly above neutral.

For example, think of a pH of 8.0 as being similar to water from a freshwater lake. It's not strongly basic like bleach or ammonia, but it still has a slightly basic nature compared to a neutral solution.

Thus, the correct option is C.
