metal compound A reacts with dilute hydrochloric acid to produce effervescence the gas evolved extinguishes a burning candle write balanced chemical equation for the reaction if one of the compounds formed in calcium chloride?
Answers
Answer:
Metal compound A = CaCO3
Gas evolved will be = CO2
When calcium carbonate reacts with hydrochloric acid, the gas so produced is carbon dioxide gas with an effervescence. As we all know, that the gas carbon dioxide is also used as a fire extinguisher. Hence, it extinguishes the burning candle. Therefore, the metal compound A is calcium carbonate. The balanced chemical equation for the reaction if one of the compounds formed is calcium chloride will be -
CaCO3 + 2HCl --- CaCl2 + CO2 + H2O
Explanation:
Explanation:
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
Equation
The balanced equation of the reaction is
CaCO3 + 2HCl → CaCl2 + CO2 + H2O
