Answer 1

$\huge\fbox\pink{ANSWER:}$

Electrolysis of water into hydrogen gas and oxygen gas, therefore, it's a chemical change and since from water(liquid) to gas conversion, therefore, physical change as well and of course it is irreversible since hydrogen gas and oxygen when in contact don't produce water.

Answer 2

Answer:

chemical endothermic reaction

Explanation:

Water electrolysis

Electrolysis of water is the chemical reaction in which the decomposition of hydrogen and oxygen gases is carried by passing an electric current. therefore it is a chemical change.

Electrolysis of water to form oxygen and hydrogen is an endothermic reaction because electrical energy is absorbed during this reaction.

so it is an endothermic reaction
