The actual yield of a product in a reaction was measured as 4.20 g. If the theoretical yield of the product for the reaction is
2 answers:
Answer:
The percentage yield of the product is 86%
Explanation:
The actual yield of product is the quantity of product that is generated in the chemical reaction as all the quantity of the compounds reacting are not consumed completely.
And the theoretical yield of product is the quantity of product that will be produced suposing that the compounds reacting were consummed completely.
The percentage of yield in a chemical reaction can be measured by the relationship between the actual yield of product and the theoretical yield of product in the following way:
%yield =
Replacing the quantities the problem gives you, we have:
%yield =
%yield = 86%

The distance - time graph of the humming bird is missing, so i have attached it.
Answer:
Instantaneous velocity = 0.5 m/s
Explanation:
From the attached graph, at time t = 1 s, the corresponding distance is 0.5 m.
Instantaneous velocity is the velocity at that point.
Thus;
Instantaneous velocity = 0.5/1
Instantaneous velocity = 0.5 m/s
