Chapter 14, Problem 4STP

Interpretation Introduction

Interpretation:

The product in the given reactionhave to be found.

Concept introduction:

Chemical reaction: Chemicalreaction is a process in which the atoms of one or more substances are rearranged and formed different substances. A chemical reaction is shown by a chemical equation. The equation should show equal numbers of atoms of each reactant and each product on both sides of the arrow.

Synthesis Reactions: Synthesis reaction is a chemical reaction in which two or more substances (A and B) react to produce a single product (AB).

$A+B\to AB$

The reaction between two elements react, is always a synthesis reaction.

Answer to Problem 4STP

Answer is B. The product is 2NOCl.

Explanation of Solution

Synthesis Reactions: Synthesis reaction is a chemical reaction in which two or more substances (A and B) react to produce a single product (AB).

$A+B\to AB$

As, it is already told that this reaction ${\mathrm{Cl}}_2(g)+2NO(g)\to$ is an example of synthesis chemical reaction, only one product will be formed. From the given options one can easily predict 2NOCl is the right answer as in the other given options all the element are not present there.

So the right equation is ${\mathrm{Cl}}_2(g)+2NO(g)\to 2NOCl$

Answer is B. The product is 2NOCl.

Conclusion

Reasons for incorrect options:

As, it is already told that this reaction ${\mathrm{Cl}}_2(g)+2NO(g)\to$ is an example of synthesis chemical reaction, only one product will be formed. From the given options one can easily predict 2NOCl is the right answer as in the other given options all the element are not present there.

So the right equation is ${\mathrm{Cl}}_2(g)+2NO(g)\to 2NOCl$

Answer is B. The product is 2NOCl. That means other options that is,

A. NCl₂

C. N₂O₂

D. 2ClOare not found by this equation that makes them incorrect.
