English to Predict Rendement of Product a Reaction

Rendement is the ratio of the amount (quantity) of oil produced from the extraction of aromatic plants. Rendemen use percent unit (%). The higher the yield value indicates that the value of the oil produced is more benyak.
Increasing the yield or the ratio of the amount of oil produced can be done with two approaches,
First, the cultivation process.
Second, the process of making oil
The quality of the oil produced is usually inversely proportional to the number of rendaments produced. The higher the resulting rendamen the lower the quality obtained. The formula for calculating the following rendamen:

Each plant has a different rendament value, below can be seen examples of some redamen values:

In 50 grams of urea fertilizer (CO (NH 2 ) 2 ) there are 21 grams of nitrogen. The purity of urea fertilizer is ...

Answer:
If you find a question that asks for purity then all you have to compare facts with theory.

FACT in Problem:
In 50 grams of urea fertilizer (CO (NH 2 ) 2 ) there are 21 grams of Nitrogen (N)

THEORY:


COMPARE:
REMEMBER yes ,, practice not to rush to use the calculator.

2.        SNMPTN 2009
If 204 grams of bauxite (Mr. Al 2 O 3 = 102) is perfectly reduced yields 54 grams of aluminum metal (Ar Al = 27). The percentage of Al 2 O 3 in the trailer is ...

Answer:
In this case we are asked to calculate the percentage of Al 2 O 3 in the snippet.
This means the trailer is not pure containing 100% bauxite.
So, our task in solving this problem is to seek the purity of the bauxite footage.
Just like the example of question 1, to do this we must also compare FACT with THEORY

FACT: Al periods produced from 204 grams of Al 2 O 3 compounds
THEORY:

Do any of you ask, why use the facts about the time of Al when the question is% Al 2 O 3 ?

Let us try by comparing the Facts and Theories of Al 2 O 3
FACT: the time of Al 2 O 3 (bauxite) is 204 grams,
THEORY: The Al 2 O 3 period in theory can be calculated from the Al period obtained from the footage



So we can conclude that we can calculate the purity of a compound just looking from the elements contained in the compound's facts and theories.

Purity (percentage) = Compare FACTS with THEORY

3.   SPMB 2004
If the reaction between 6 grams of ethane C 2 H 6 (Mr = 30) with 7.1 grams Cl 2 (Mr = 71) yields 5.16 grams of C 2 H 6 Cl (Mr = 64.5) then the percentage of the yield of ethylchloride is. ..

Answer:
In this case we are asked to calculate% C 2 H 6 Cl, so let's compare facts and theories:

FACT:
The C 2 H 6 Cl period generated = 5.16 grams



THEORY:

We are looking for the C 2 H 6 Cl period generated from the reaction


The reaction is happening


Theoretically C 2 H 5 Cl produced from the reaction is 0.2 mol

      The yield relative used as the calculation of the effectiveness of the procedure, is calculated by dividing the number of products obtained in moles with theoretical yield in moles:

      Yes, because the yield of the theoretical calculated based on the number of moles of the limiting reagent. For this calculation, it is usually assumed that there is only one reaction involved.
