Answer:
Chemical Reactions. ... Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules.
The atomic number of an element never changes no matter how many neutrons they have so Sulfur would just have an atomic number of 16 like normal.
The balanced chemical reaction is:
<span>2H2+O2-->2H2O

To determine the mass of hydrogen that is needed, we need use the initial amount of oxygen and relate it to hydrogen from the reaction given. We do as follows:
192 g O2 ( 1 mol O2 / 32 g O2) ( 2 mol H2 / 1 mol O2 ) ( 2.02 g H2 / 1 mol H2 ) = 24.24 g H2
