Question

which pair of substances would most likely result in the production of a gas when reacting with an acid

Answer 1

Both metals and carbonates reacts with acids to produce gases. Metals for instance, react with acids to yield a salt and hydrogen gas. For example when zinc metal reacts with hydrochloric acid, a salt of zinc chloride and hydrogen gas are formed. Hope that helped out (:

Answer 2

C. metal and carbonate

Step-by-step explanation:

Gas is known as the state of matter that has no shape or volume of its own. It is composed mainly of molecules not united, expanded and with little force of attraction to each other, which makes it have a defined shape and volume, so it expands and occupies the entire volume of the container it contains.

Gases can be formed by chemical reactions that mix two different elements, but there is no chemical reaction that has this capacity. Among the options given in the question above, we can say that a chemical reaction that has as reagents metal and acid or a carbonate and acid can result in gases.
