write the chemical equation for the chemical reaction takes place when thus formed compound is threated with the hydrochloric acid |
|
Answer» The GAS thus formed is an effervescent carbon dioxide gas when calcium carbonate reacts with hydrochloric acid. The carbon dioxide gas also acts as an extinguisher for fires. Hence, the BURNING candle is extinguished. The metal compound A, therefore, constitutes calcium carbonate. Hence metal compound A is CaCO3 The Gas evolved is CO2 CaCO3 + 2HCl → CaCl2 + CO2 + H2O |
