Answer 1

The number of hydrogen atoms after the reaction depends on what type of chemical reaction is occurring. If the reaction does not involve the addition or removal of hydrogen atoms, the number of hydrogen atoms will remain the same. Therefore, if there are 4 atoms of hydrogen before the reaction, there will also be 4 atoms of hydrogen after the reaction.

So the correct answer is 4.
