How many moles of water are produced when 3.0 moles of hydrogen gas react with 1.8 moles of oxygen gas?

balanced equation: 2h2 + o2 → 2h2o
3.0 moles of water
3.6 moles of water
5.3 moles of water
7.0 moles of water

What is the overall order of reaction for rate = k[no]2[o2]

Ineed ! i have no clue how to do this problem.

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
