Consider the Haber Process:
N2(g) + 3H2 (8) ---> 2 NH3(g)
How many grams of ammonia are produces when 340.0 g of nitrogen reacts with 100.0 g of hydrogen? (Show
all work)
What is the limiting reactant?
What is the excess reactant?

60.0 - there are 3 significant numbers

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
