N2+ 3H2 → 2NH3 How many moles of hydrogen, H2, are needed to react with 2.0 moles of
nitrogen, N2?

( pls give explanation :] )

Tell me the iupac name of the following compounds:

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

The identities of substances are the same before and after which type of change
