The law of conservation of matter states that matter cannot be created or destroyed. this law applies when a chemical change occurs. the number of atoms present before a chemical change is the same as the number of atoms present after the change. the atoms may be combined in a new way, but the overall number of atoms remains unchanged. using the law of conservation of matter, if i started an experiment with 200 atoms of matter, how many atoms would i have after the chemical change? question 1 options: 100 200 300 400

It says it will never change. So whatever it was before the change, it will be the same after the change. So, 200 should be correct.
