Me with chemistry questions? 1. when an electric current is passed through liquid water, hydrogen gas accumulates at one electrode and oxygen gas accumulates at the other. which of the following is true? a) a physical change has occurred with energy being absorbed b) a chemical change has occurred with energy given off c) a physical change has occurred with energy given off d)a chemical change has occurred with energy being absorbed

The answer is option D

That is when an electric current is passed through liquid water, hydrogen gas accumulates at one electrode and oxygen gas accumulates at the other, a chemical change has occurred with energy being absorbed.  

This process is called electrolysis of water in which hydrogen gas accumulates at one electrode and oxygen gas accumulates at the other. In it decomposition of water occurs chemically using electricity as the energy source.  

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.
