Astudent places a 12-gram cube of ice inside a container. after six hours, the student returns to observe the contents of the container. which sentence suggests that the container is an open system? a. the container contains 12 grams of liquid water and no ice. b. the container contains 12 grams of ice and no liquid water. c. the container contains 8 grams of liquid water and no ice. d. the container contains 8 grams of ice and 4 grams of liquid water. e. the container contains 8 grams of liquid water and 4 grams of water vapor.

- C. The container contains 8 grams of liquid water and no ice.

Explanations:- In thermodynamics, "An open system is the one that exchanges energy and matter with it's surroundings."

If we look at all the choices then the total mass is 12 grams except for choice C. So, the correct choice is C as the mass in the container remains 8 grams since some of the amount is lost to the surroundings in the form of water vapors.

if you mean hydrogen and oxygen then water is the product
