For this question, we have a reaction between barium hydroxide and sulfuric acid to give us water in barium sulfate.
00:06
And we want to know if we are starting with two moles of barium hydroxide first, how many moles of sulfuric acid are going to be needed? and then our second and third part of this question is how many moles of each of our products can we make? so how many moles of barium sulfate can we make? and how many moles of water can we make? so we're going to have three short setups.
00:29
So we're first going to start with our two moles.
00:32
Of barium hydroxide.
00:37
And then using the coefficients from the balanced chemical reaction, we're going to set up a mole ratio to convert between, in this case, starting with sulfuric acid, and then we'll do the same thing to convert to water and barium sulfate as well.
00:49
So we're going to have our mole ratio.
00:52
We've got one mole of sulfuric acid on top, and then one mole of barium hydroxide on the bottom.
01:01
And so we're going to get two moles of sulfuric acid is needed.
01:06
And that's our first answer.
01:11
So next, we're going to convert to moles of barium sulfate...
