Question 1 • Physical Science

Liquid 1 reacts with Liquid 2 , producing a solid and a gas. Using this scenario, which supports the law of conservation of mass?

Answer
A
mass of liquid 1 plus mass of solid is equal to mass of liquid 2 plus mass of gas
B
mass of liquid 1− mass of liquid 2=mass of solid +mass of gas
C
mass of liquid 1 minus mass of solid is equal to mass of liquid 2 minus mass of gas
D
mass of liquid 1+ mass of liquid 2=mass of solid +mass of gas
