Question

Какой газ выделяется при смешивании карбида кальция и воды?

Answer 1

АЦЕТИЛЕН
CaC2 + 2H2O --> Ca(OH)2 + C2H2

Answer 2

Gas Released from Mixing Calcium Carbide and Water

When calcium carbide (CaC2) is mixed with water (H2O), it produces acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2) as shown below:

CaC2 + 2H2O → C2H2 + Ca(OH)2.

The reaction of calcium carbide with water is a well-known method for producing acetylene gas, which has various industrial applications, including welding and metal cutting.

This reaction is also exothermic, meaning it releases heat as a byproduct
