Answer:
Given theoretical yield of NH3 is 945g.
The actual yield is 598g.
What is the %yield?
Explanation:
%yield of a chemical reaction can be calculated by using the formula:
Substitute the given values in this formula to get the %yield.
Hence, the %yield for the formation of ammonia is ---- 63.3.
Answer:
Explanation:
The law of multiple proportions say that two elements, A and B, are able to combine with each other to form distinct compounds, the different masses of B that bind to a certain mass of A, are in relation of integers and simple numbers.
2SO₂ → S₂ + 2O₂
Mass S₂=2 . 32g= 64g
Mass 2O₂=4 . 16g=64g
∴ 64/64=1 ⇒ One produced 1.002 g S for every gram of O, the relation is 1:1
2SO₃ → S₂ + 3O₂
Mass S₂=2 . 32g= 64g
Mass 3O₂=6 . 16g=96g
∴ 64/96= 2/3 ⇒ It is produced 0.668 g S for every gram of O, the relation is 2:3.
To sum up, these results are consistent with the law of multiple proportions because the results are integers and simple numbers.
I hope I help you!
