How many moles are AgNO, are produced from 40 moles of HNO, according to the following reaction:
3Ag + 4HNO3 3AgNO, + 2H2O + NO
A.10 mol AgNO3
B.20 mol AgNO3
C.30 mol AgNO3
D.40 mol AgNO3

It is true about the type of reaction that it is a single replacement reaction, and the cations in the two ionic compounds are different.

Explanation:

When one element in a compound is replaced by another element in a chemical reaction then it is called a single replacement reaction.

For example,

Here, potassium metal is replacing the sodium metal in the sodium chloride compound.

As metals become cation by losing an electron in a chemical reaction.

Thus, we can conclude that it is true about the type of reaction that it is a single replacement reaction, and the cations in the two ionic compounds are different.
