Which equation obeys the law of conservation of mass? H2(g) + O2(g) → H2O(g) H2(g) + O2(g) → H2O(g) +4He(g) 2H2(g) + O2(g) → 2H2O(g) H2(g) → H2O(g) H2(g) + O2(g) → 2H2O(g)

Explain the relationship between forward and backward reactions in equilibrium, and predict how changing the amount of a reactant (creating a tension) will affect that relationship.

What is the subscript for oxygen in its molecular formula

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.
