Using the following equation, if you used 20 moles of O2, how many moles of H2O would be produced? 2H2 + O2 → 2H2O

a)10 mol
b)40 mol
c)5 mol
d)20 mol

Ibelieve the answer is b.2200 watts, because p=vi; p=220(10); then p=2200hope my answer has you : )

The population of unionid mussels decreased after zebra mussels were introduced. zebra mussels competed with the unionid mussels for food. the zebra mussels were able to displace the unionid mussels, allowing the zebra mussel population to increase  over the years. the unionid mussel population decreased because  of lack of food.
