Question

Please answer this... This is due tomorrow... How can you tell the mass was conserved in a chemical reaction?

Answer 1

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reaction

Answer 2

Step-by-step explanation:

Perform an experiment is a closed system (nothing can escape).

For example AgNO3 is soluble in water. So is NaCl

Put 10 grams of AgNO3 in 100 grams of water. Stir well.

Put 10 grams of NaCl in 100 grams of water.

Weigh the two containers to get the total mass. Weight them together.

Let's say you get 300 grams all together. (The beakers weigh something).

Now mix the two together. Weigh everything again including the empty beaker.

Everything should weigh what it did before, but you notice there is a white mass at the bottom that wasn't there before. There was a reaction, but no loss of mass.
