How many moles of water are produced by the reaction of 2.0 mol of H3PO4 with 6.0 mol of NaOH?

Question

I think it's either 4 or 6?

(a) 2.0 mol
(b) 4.0 mol
(c) 6.0 mol
(d) 12 mol

Answer 1

Count the hydrogen and oxygen atoms produced by the reaction. In 2 mol H3PO4, you have 6 H's. In 6 mol NaOH, you have 6 H's and 6 O's (you actually have six OH(-) molecules, but I don't want to get too deep here). Twelve H's and six O's make six H2O's.

(c) 6.0 mol

Answer 2

answer B 4.0 mol First you may write and stability the equation. H3PO4 + 3NaOH yields Na3PO4 + 3H2O This tells you for each a million mole of H3PO4 you will possibly produce 3 moles of H2O or for each 3 moles of NaOH you will possibly produce 3 moles of H2O on account which you have 2 moles of H3PO4 and 6 moles of NaOH you produce 4 moles of H2O (there is not any proscribing reagent)

Answer 3

6 is right. The first ionized H+ produces 2 mol of water. The second ionized H+ produces another 2 mol of water, and the last H+ to ionize produces another 2 mol of water. Totaling 6 mol of water produced.

Answer 5

if we assume that all the Hydrogen reacts to form water then we have
2mol x H3P04=6mol H + 2mol P + 8mol O and
6mol xNaOH=6mol Na + 6mol H 6 + 6mol O

We have 12 moles of H which can make 6 moles of H20

we then have to figure out if there is enough oxygen to make 6 moles of H2O
There are 6 moles of oxygen in 6 moles of H20 so we only need the 6 Moles of oxygen that is in NaOH to have enough.

that means we would get 6 moles of H20 and that is your answer

Answer 6

c) 6.0 The reaction from a total point of view is:

H3PO4 + 3 NaOH ---> Na3PO4 + 3 H2O

For every mole of phosphoric acid you get 3 moles of water.

Answer 7

c) Verify by looking at the balanced equation
