When sulfur burns, it forms sulfur dioxide (SO2). Its chemical reaction is S + O2 → SO2.
Elenna [48]

Answer:

The mass of SO2 will be equal to the sum of the mass of S and O2.

Explanation:

This can be explained by the <em>Law of Conservation of Mass</em>. This law states that mass can neither be created nor destroyed. Knowing this, we can say that the reactants of a chemical reaction must be equal to the products.

In this case, the reactants Sulfur (S) and Oxygen (O2) must equal the mass of the product Sulfur Dioxide (SO2). Therefore, the statement <em>"The mass of SO2 will be equal to the sum of the mass of S and O2" </em>is correct.

During an exothermic chemical reaction, a solid is consumed and a gas produced. a. Yes b. No c. Can't decide with information gi
kiruha [24]

<u>Answer:</u> The given statement is true.

<u>Explanation:</u>

For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.

The equation used to calculate Gibbs free energy follows:

\Delta G=\Delta H-T\Delta S

Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change (\Delta H) of the reaction comes out to be negative for this kind of reaction.

Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as (\Delta S). Randomness of gaseous particles is more than that of liquid which is further more than that of solids.

We are given:

A solid substance is converting into a gaseous substance.

\text{Solid}\rightarrow \text{Gas}

As, the entropy is increasing. So, the entropy change is positive.

Thus, the above reaction is spontaneous.\Delta G=-ve-(+ve)\\\\\Delta G=-ve

Hence, the given statement is true.
