Iron combines with oxygen to form rust. given the chemical reaction, how many grams of rust would be produced if 3 grams of reactants were consumed? a) 0 grams b) 1 gram c) 3 grams d) 7 grams

Hello!

If 3 grams of reactants were consumed, then C) 3 grams of rust must be produced.

There are two possible chemical reactions between iron and oxygen to form rust:

These two chemical reactions obey the Law of Conservation of Matter, which states that matter is conserved in a chemical reaction.

So, if there are 3 grams of reactants initially, and they react completely, then 3 grams of rust (either Ferrous Oxide or Ferric Oxide) must be produced for the reaction to obey the Law of Conservation of Matter.

Have a nice day!

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
