Question

CaCO3 = ..... +CO2 C4(OH)2 = C4O + .... NH4Cl = ..... +HCL

Answer 1

Ответ:

CaCO₃ = CaO + CO₂

C₄(OH)₂ = C₄O + H₂O

NH₄Cl = NH₃↑ + HCl

Answer 2

These chemical equations represent the decomposition reactions of the given compounds into their constituent elements or simpler compounds:

1. CaCO3 (calcium carbonate) decomposes into CaO (calcium oxide) and CO2 (carbon dioxide): CaCO3 → CaO + CO2

2. C4(OH)2 (a hypothetical compound) decomposes into C4O (a hypothetical compound) and H2O (water): C4(OH)2 → C4O + 2H2O

3. NH4Cl (ammonium chloride) decomposes into NH3 (ammonia) and HCl (hydrochloric acid): NH4Cl → NH3 + HCl

Please note that the decomposition of hypothetical compounds like C4(OH)2 and C4O is not based on any real chemical compounds, so these equations are purely hypothetical.
