A student begins an experiment with 200 grams of a reactant and ends with 175 grams of product. What most likely happened to the missing 25 grams?
A The 25 grams remained in the reactant.
B. The 25 grams were lost due to excessive pressure.
c. The 25 grams escaped as a gas.

Sorry i dont understand the question can you rephase it?

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
