Na₂S₂O₃(aq) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + SO₂(g) + S(s). A light yellow precipitate develops as the process continues.
<h3>What does the chemistry term "equation" mean?</h3>
Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.
<h3>Equation and response are what?</h3>
What is an equations and a chemical reaction? In a chemical change, bonds between molecules of the reagent are destroyed and new bonds between molecules of the product are established to create a new substance. A chemical formula is nothing more than a statement of fact that represents how reactants generate products.

Answer:
Explanation:
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Loss of an electron is oxidation!
<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:
Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change 
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 
. 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.
As, the entropy is increasing. So, the entropy change is positive.
Thus, the above reaction is spontaneous.
Hence, the given statement is true.
It would become a negative ion
