Write a hypothesis to answer the lesson question "How can electrolysis be used to separate a
compound into its components?"
If (an electrical current, a salt, an electrode, or oxygen)?
is applied to water
containing an electrolyte, then the water will
decompose into( water vapor, sodium gas, hydrogen gas, oxygen gas, hydrogen and oxygen gas)?
because?

Electric current

Hydrogen and oxygen gas

Explanation:

Electrolysis is defined as a method of separation whereby an electric current is introduced into compounds to separate them . The electric current used here is a direct electric current (DC) and it makes the compound to be spit into its' component elements.

Now, in the case of water like it says in the question. Water is a mixture of hydrogen and oxygen gas. Thus, when electric current is passed through water which has an Electrolyte, it makes the water to decompose into its compound elements which are hydrogen and oxygen.
