Question

1. build the chemical equation for the decomposition of water via electrolysis. i need a hint ab → a + b choices: h h₂ h₂o h₂o₂ o o₂ 0 / ∞ submissions used score: 0/1

Explanation:

Step1: Identify water formula

Water is represented as $H_2O$.

Step2: Recall products of electrolysis

Electrolysis of water produces hydrogen gas ($H_2$) and oxygen gas ($O_2$).

Step3: Balance the equation

The balanced chemical equation is $2H_2O\xrightarrow{electrolysis}2H_2 + O_2$.

Answer:

$2H_2O\xrightarrow{electrolysis}2H_2 + O_2$
