Answer: No it does not
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed and in this equation you start with 1 molecule of Cl and 1 of H, but on the reactants side you end up with 2 of each. To make it follow the law of conservation of mass you would have to balance the equation
Answer:
I know its not Oxygen (O2) because we need that gas to breath if not more of that gas! and i know its not helium because it is not very toxic and not a crisis in the world
Your answers are going to be B. and D.

Some things that can indicate a chemical change are change of odor, change of color, change in temperature or energy, such as the production or loss of heat. An example could be the rusting of metal, there would be a color change of going from a shiny silver to a dirty, splotchy red color. Some things that indicate a physical change are change of appearance like change of shape, etc. It can also be like a change between a solid to liquid to gas. For example, the cutting of a piece of paper.
If I remember correctly, it would be B. A very large amount of energy is produced from a tremendous mass.
