Since the mass of of the helium nucleus is approx. 4.00 amu
Answer:
The percentage yield is 80.36% (see calculations in attachment).
Explanation:
The theoretical yield of the reaction is the <u>amount of product that would result if all the limiting reagent reacted.</u> The theoretical yield is calculated using the balanced equation.
In practice, the actual yield, or the <u>amount of product actually obtained from a reaction</u>, is almost always less than the theoretical yield.
To determine how efficient this reaction is, we need to calculate the percent yield, which describes the <u>proportion of the actual yield to the theoretical yield.</u> It is calculated as follows:

First we need to make sure that the equation is properly balanced. In the question they provide the balanced equation.
Since water is in excess, we calculate the theoretical yield using PCl₃.
Answer:
fe2o3 + 6hcl => 2fecl3 + 3h2o
Explanation:
Answer:
Pilot scale up
Explanation:
Preformulation studies are carried out on candidate drug molecules that show sufficient pharmacological promise in animal model(pharma approach).
It involves preliminary study of the properties of a drug which is considered a potentially active ingredient against a particular disease condition.
Scale-up is the term used to refer to the increase in the batch size of a product. This is only done after a drug has been proven successful against the target disease after extensive pilot studies.
Scale-up is the last operation carried out when a drug has passed through all stages. It is not included in preliminary preformulation studies
6 Li + N2 = 2 Li3N
6 moles Li ---------> 2 moles Li3N
0.24 moles Li ------> ?
moles Li3N = 0.24 * 2 / 6
= 0.48 / 6
= 0.08 moles of li3N
hope this helps!.
