Metal compound A reacts with dilute hydrochloric acid to producecilervescence. The gas evolved extinguishes a burning candle Write abalanced chemical equation for the reaction if one of the compoundsformed is calcium chloride. |
Answer» because metal is lees reactive from hydrogen When calcium carbonate reacts with hydrochloric acid, it produces carbon dioxide gas with effervescence. Carbon dioxide used as fire extinguisher. Hence, it extinguishes a burning candle. Therefore, the metal compound A is calcium carbonate. CaCO3+ 2HCl ⇨ CaCl2+ CO2+ H2O |
