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

vovangra [49]

Answer: metal and carbonate

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydrogen ions $(H^+)$ in water.

An acid is represented as :

$HX\rightarrow H^++X^-$

1. When metal is treated with an acid such as $HCl$ , if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.
