Problem 92P

Classify each chemical reaction as a synthesis, decomposition, single-displacement, or double-displacement reaction.

(a)Β \(\mathrm{CaSO} 4(g) \underset{\text { heat }}{\longrightarrow} \mathrm{CaO}(s)+\mathrm{SO}_{3}(g)\)

(b)Β \(2 \mathrm{Na}(s)+\mathrm{O}_{2}(g) \rightarrow \mathrm{Na} 2 \mathrm{O} 2(s)\)

(c)Β \(\mathrm{Pb}(s)+2 \mathrm{AgNO}_{3}(a q) \rightarrow \mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}(a q)+2 \mathrm{Ag}(s)\)

(d)Β \(\mathrm{HI}(a q)+\mathrm{NaOH}(a q) \rightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{Nal}(a q)\)

Equation Transcription:

CaSO4(𝘨) CaO(𝑠) + SO3(𝘨)

2 Na(𝑠) + O2(𝘨)Na2O2(𝑠)

Pb(𝑠) + 2 AgNO3(π‘Žπ‘ž)Pb(NO3)2(π‘Žπ‘ž) + 2 Ag(𝑠)

HI(π‘Žπ‘ž) + NaOH(π‘Žπ‘ž)H2O(𝑙) + NaI(π‘Žπ‘ž)

Text Transcription:

CaSO_4(𝘨) heat^rightarrow CaO(𝑠) + SO_3(𝘨)

2 Na(𝑠) + O_2(𝘨) rightarrow Na2O2(𝑠)

Pb(𝑠) + 2 AgNO_3(π‘Žπ‘ž) rightarrow Pb(NO_3)_2(π‘Žπ‘ž) + 2 Ag(𝑠)

HI(π‘Žπ‘ž) + NaOH(π‘Žπ‘ž) rightarrow H_2O(𝑙) + NaI(π‘Žπ‘ž)

Step-by-Step Solution:
Step 1 of 3

Solution 92P

Here, we have to find out the type of each reaction.

Synthesis:Β When two or more molecules combine together to form a new compound is called synthesis.

Decomposition :It is a chemical reaction where a single compound splits into two or more simple substances under suitable conditions.

Single displacement reaction:Β It is a chemical reaction where an element reacts with a compound and takes the place of another element in that compound.

Double displacement reaction: It is a chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants interchange their places, forming two new compounds or products.

(a)Β 

It is a Decomposition Β reaction.

(b)Β 2 Na(s) + O2(g) β†’ Na2O2(s)

It is a Synthesis process.

(c)Β Pb(s) + 2 AgNO3(aq) β†’ Pb(NO3)2(aq) + 2 Ag (s)

It is a Single displacement reaction.

(d)Β HI(aq) + NaOH(aq) β†’ H2O(l) + NaI(aq)

It is a Double displacement reaction.
