Question

what happens when --
(a) solid sodium hydrogen carbonate is heated ?
(b) an acid reacts with a metal ? Give chemical reactions in both​

Answer 1

Answer:

Sodium hydrogen carbonate has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide.This type of reaction is called a thermal decomposition

b) Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas.
