Helium can be liquefied when he atoms are attracted to one another by intermolecular forces.

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

We are hoping to create 5.72 grams of glucose. the plant was given 4.75 liters of co2 and 2.81 g of h20. which reactant was the limiting reagent? how much excess mass did we have of the other reactant?

Consider this reaction taking place in a closed 2 liter container: 2so2(g) + o2(g) → 2so3(g) if the volume of the container is decreased to 1 liter, what will happen to the equilibrium of the reaction? it will shift left. it will shift right. it will remain constant it will decrease by half
