Question

1. the decomposition of water can be accomplished when electricity is applied to water. this process is known as electrolysis. the interactive shows a miniature hoffman apparatus that is used to run electricity through water. when the source of voltage is activated, the decomposition of water begins. the products of the decomposition are gasses collected in two test tubes. near the halfway point of the video, you will see a splint test performed on gas 1 (left test tube). observe and listen to the results of the splint test. identify the product of the gas formed in test tube 1. what is a splint test? gas 1 is a gas that isnt any of the 3 options gas 1 is steam (h₂o) gas 1 is hydrogen gas 1 is oxygen the small explosion suggests that this gas is

Explanation:

A splint test is a common laboratory test in chemistry. When hydrogen gas is present and a lit splint is introduced, it causes a small explosion (a 'pop' sound). In the electrolysis of water, hydrogen gas is produced at the cathode. The description of a small explosion in the splint test indicates that the gas in test - tube 1 is hydrogen.

Answer:

Gas 1 is hydrogen
