Answer:

mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas

Explanation:

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

of mass?

EEEE

O mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas

O mass of Liquid 1 - mass of solid = mass of Liquid 2-mass of gas

O mass of Liquid 1 - mass of Liquid 2 = mass of solid + mass of gas

O

based on the law of the conservation of matter, the sum of the masses of the reactants must equal  the sum of the masses of the products

so the correct answer is

mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas
