Question

For the following reaction, 3.45 grams of sulfuric acid are mixed with excess calcium hydroxide. The reaction yields 4.49 grams of calcium sulfate.


H2SO4 (aq) + Ca(OH)2 (s)= CaSO4 (s) + 2 H2O (l)





(1) What is the theoretical yield of calcium sulfate ?

grams



(2) What is the percent yield for this reaction ?

%

Answer 1

ok so sulfur is 32

Answer 2

yes

Answer 3

calcium sulfate is 40

Answer 4

Find the molecular weight of the sulfuric acid first.

Answer 5

98.078

Answer 6

yes. Now change the 3.45 grams of sulfuric acid to moles of sulfuric acid

Answer 7

is it .03517

Answer 8

yes. So how many moles of calcium sulfate will be produced according the the balanced equation?

Answer 9

You need to answer my question

Answer 10

Look at the balanced equation.

Answer 11

It says 1 mole of sulfuric acid reacts with 1 mole of calcium hydroxide to produce 1 mole of calcium sulfate and 2 moles of water.

Answer 12

It is absolutely critical that you understand that.
