8.5L H2O (1 mol H2O/22.4L)=.37946 mol H2O
.3796 mol H2O(1 mol CH4/2 mol H2O)=.18973 mol CH4
.18973 mol CH4(22.4L/1mol CH4)=4.25L CH4 gas
Bromate anion I hope this helps.
First option is the right answer Goodluck

Water typically exist in its gaseous state in the atmosphere. Fog contains droplets of liquid water suspended in the air. Thus to produce a fog, vapor in the air would undergo condensation with a state change from gas to liquid.
Intermolecular interactions between water molecules strengthen as the vapor condenses to produce a liquid. The condensation of vapor thus involves a production of energy. With all the extra intermolecular interactions, molecules in the fog would find it more difficult to move around and therefore see a decrease in their motion.
