Answer:
%age Yield = 42.9 %
Explanation:
Percentage Yield is defined as the actual yield divided by theoretical yield. It is given as,
%age Yield = Actual Yield / Theoretical Yield × 100 --- (1)
Also,
Actual Yield is the amount of desired product which is obtained after an experiment is completed. We can also call it the real yield which is obtained practically. While, theoretical yield is the yield which is calculated on paper. Hence, we can say that the actual yield is always less than theoretical yield due to many reasons including reaction conditions and researcher handling problems.
Thus we are given following data;
Theoretical Yield = 1.70 g
Actual Yield = 0.73 g
Putting these values in Eq. 1,
%age Yield = 0.73 g / 1.70 g × 100
%age Yield = 42.9 %
The given chemical equation represents the combustion reaction of propanoic acid:
On balancing we get,
The above balanced chemical equation tells us that, 2 mol require 7 mol for complete combustion to produce and
Given moles of = 1 mol
Calculating moles of required for combustion:
Therefore, 3.5 mol Oxygen is required for complete combustion of 1 mol propanoic acid.
Answer:
Coefficient of water is 1
Explanation:
The balanced equation;
3NO2 + H2O --> 2HNO3 + NO
;Firstly balance the hydrogen atoms
;Then balance the nitrogen atoms....in which this would also balance the oxygen atoms
Answer:
No.
Explanation:
No. There is 1 atom of Ca on the left and 2 Ca's on the right and 2 OH's on the left and 4 on the right.
The balanced equation is:
4OH- + 2Ca2+ ----> 2Ca(OH)2.
