What is the perecentage yield of a reaction in which 200g PCl3 reacts with excess water to form 128g HCl according to the f.F re
castortr0y [4]

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:

%yield = actual yield ÷ theoretical yield × 100%

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.

Preliminary preformulation studies for a new candidate drug molecule does not include one of these
devlian [24]

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

How many moles of Li3N will be created using 0.24 moles of Li in the given reaction? 6Li + N2 2Li3N
andreyandreev [35.5K]
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!.
