Question

in a chemical reaction, two clear solutions are mixed in a sealed beaker to form a yellow solid. what will happen to the total mass of the beaker? a it will decrease because solids are lighter b it will increase because the reaction made new matter c it will stay the same because matter is conserved d it will decrease because gas escaped

Explanation:

According to the law of conservation of mass, in a closed - system (the sealed beaker in this case), the total mass of substances before and after a chemical reaction remains the same. Matter is neither created nor destroyed in a chemical reaction, only rearranged.

Answer:

C. It will stay the same because matter is conserved
