How many water molecules are there in the equation ch4 + 202

None, unless a single displacement reaction takes place. There is 4 hydrogen and 4 oxygens which could potentially make 2 water molecules (H2O). I’m not entirely sure though.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

Ithink 2 is the correct
