In the product 6O2, what does the coefficient mean?

There are 12 molecules of O2,

There are 8 molecules of O2,

There are 6 molecules of O2.

There are 2 molecules of O2.

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

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

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

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

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