Answer 2

Answer:

For a: The reaction is combination reaction.

For b: The reaction is neutralization reaction.

For c: The reaction is single displacement reaction.

For d: The reaction is decomposition reaction.

Explanation:

• For a:

A combination reaction is a type of chemical reaction in which two or more substances join together to form a single molecule. General equation for this reaction is:

$A+B\rightarrow AB$

So, $CaO+SiO_2\rightarrow CaSiO_3$ is an example of combination reaction.

• For b:

A neutralization reaction is a type of chemical reaction in which an acid reacts with a base to produce a salt ans water molecule. General equation for this reaction is:

$HX+BOH\rightarrow BX+H_2O$

So, $KOH+HCl\rightarrow KCl+H_2O$ is an example of neutralization reaction.

• For c:

A single displacement reaction is a type of chemical reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction. General equation for this reaction is:

$A+BC\rightarrow AC+B$

where, A is more reactive than B.

So, $Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$ is an example of single displacement reaction.

• For d:

Decomposition reaction is a type of chemical reaction in which a single molecule breaks down into two or more molecules. General equation for this reaction is:

$AB\rightarrow A+B$

So, $BaCO_3\rightarrow BaO+CO_2$ is an example of decomposition reaction.
