Acid rain occurs when sulfur dioxide in the atmosphere is oxidized in the presence of nitrogen dioxide. Acid rain is an example
Bas_tet [7]

Answer:

B. Secondary pollutant

Explanation:

A primary pollutant is directly emitted into the atmosphere. Volcano eruptions and emissions from cars can result in primary pollutants in the air.

Secondary pollutants are not directly put in the atmosphere. They are created when two or more primary pollutants in the atmosphere react. One example is smog.

Another example is acid rain. If sulphur dioxide, nitrogen dioxide and water react, then acid rain is formed. Therefore, acid rain must be a secondary pollutant.

The best answer choice is B. secondary pollutant

Which change will cause more CO2 to form in a closed container?​
EastWind [94]

Answer:

Option C Removing Na₂CO₃

Option E Heating the container.

Explanation:

The equation for the reaction is given below:

2NaHCO₃ (s) <=> Na₂CO₃ (s) + CO₂ (g) + H₂O (g)

Enthalpy change (ΔH) = 136 KJ

To obtain more CO₂ do the following:

1. Add more NaHCO₃

From chemical equilibrium, adding more NaHCO₃ means the reactant has increase. Thus, it (the reactant) will react to form more product (CO₂)

2. Removing any of the products. Removing any of the products implies that more reactants are in the reaction vessel than the product. Thus, the reactants will react to produce more products (CO₂)

3. Heating the container. Heating the container will lead to an increase in the temperature of the reaction. Since the enthalpy change (ΔH) is positive it means the reaction is endothermic. Thus, heating the container i.e increasing the temperature will favours the forward reaction i.e more products will be obtained.

NOTE: Pressure has no effect in the reaction system since there is no gaseous reactants.

Considering the options given above, C and E gives the correct answer to the question.
