Question

In a chemical reaction represented by the general equation A+ B = C + D, there are 4 distinct mole ratios that can be written. True or false?

Answer 1

So,

These species react stoichiometrically. Thus, we can say, for example, that 1 mol A is stoichiometrically equivalent to 1 mol B in this reaction. I will say A = B.

A = B

A = C

A = D

B = C

B = D

C = D

As you can see, there are more than 4 distinct mole ratios for this reaction. Thus, the statement is false.

Answer 2

The statement is False Statement.

Step-by-step explanation:

we are given a chemical reaction represented by the general equation

A + B = C + D,

since we are not given information regarding number of moles of any of A, B , C or D that are part of the chemical reaction so we take it to be equal to one mole by default.

so since in the given equation each of A, B, C, and D have equal no. of moles say equal to 1 then according to the given equation there can not be 4 distinct mole ratios hence the answer is false.
