Answer:
8 moles SO₂
Explanation:
To find the moles SO₂, you need to multiply the given value by the mole-to-mole ratio. This ratio, between O₂ and SO₂, is made up of the coefficients from the balanced equation.
2 H₂S + 3 O₂ -----> 2 SO₂ + 2 H₂O
12 moles O₂ 2 moles SO₂
-------------------- x ---------------------- = 8 moles SO₂
3 moles O₂
Answer:
I think B is the answer so hope
Hey there!:
1 mole of FeSO4 = 151.8 g/mol
25.0 g change to mole = 25.0 / 151.8
moles of FeSO4 = 0.165 moles
One mole of any substance has 6.02*10²³ units
0.165 moles to get the number of Fe ( II ) ions :
number of Fe(II) ion = 0.165 * ( 6.02*10²³ )
number of Fe ( II ) ion = 9.93*10²² units
Answer:
The percent yield of this reaction is 84.8 % (option A is correct)
Explanation:
Step 1: Data given
The student isolated 15.6 grams of the product = the actual yield
She calculated the reaction should have produced 18.4 grams of product = the theoretical yield = 18.4 grams
Step 2: Calculate the percent yield
Percent yield = (actual yield / theoretical yield ) * 100 %
Percent yield = (15.6 grams / 18.4 grams ) * 100 %
Percent yield = 84.8 %
The percent yield of this reaction is 84.8 % (option A is correct)
