Help please and thank you. N2(g) + 3H2(g) → 2NH3(g)

How many moles of N2 will react with 1.5 moles of H2?

This is a mixture that has the same composition throughout.

Consider the nuclear equation below. 239/94 pu—-> x+ 4/2 he. what is x?

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
