Answer 5

ok and?

Answer 6

The reaction is always driven according to the limmiting reactant. So despite the fact that 7.6 moles of H2O is present, only 7.5 moles of it will react with 7.5 moles of Na

Answer 7

ok

Answer 8

and this will produce 7.5 moles of NaOH and 3.25 moles of H2

Answer 9

so NaOH is 7.5 moles?

Answer 10

yes, now you need to calculate the mass of 7.5 moles of NaOH

Answer 11

It will be 7.5 moles X molar mass of NaOH (which is 40)

Answer 12

ok

Answer 13

NOw again find the mass of 3.25 moles of H2. And finally add both the masses to get the final mass of products.

Answer 14

how about the 2 in NaOH?

Answer 15

Have you read your chapter carefully ?

Answer 16

do you have some websites of this.. ?
