Question

Place the letter corresponding to each of the reaction types in the column to the right of each chemical reaction. List all that apply. Each reaction may be described by one or two reaction types.

Answer 1

Explanations

4) According to the question, we are to determine which type of reaction are the given reaction by using the given reactions in the table.

The reaction between lead (II) hydroxide and hydrochloric acid to produce lead(II) chloride and water is an acid-base reaction that involves the reaction between an acid and base to produce salt and water

`Pb(OH)___2+2HCl\rightarrow PbCl_2+2H_2O\text{ \lparen Acid-Base reaction\rparen}`

For the second reaction:

`4C_4H_9O(g)+29O_2(g)\rightarrow20CO_2(g)+18H_2O(g)\text{ \lparen combustion\rparen}`

This reaction is a combustion reaction since it occurs under oxygen to produce carbon dioxide and water.

For the third reaction:

`6HBr+2Al(OH)_8\rightarrow2AlBr_3+3H_2O(DoubleDisplacement)`

This is a double displacement reaction since it involves the reaction between two compounds to produce another two compounds.

For the fourth reaction given as:

`4Fe+3O_2+6H__2O__\rightarrow4Fe(OH)_3\text{ \lparen synthesis combination\rparen}`

This is a synthesis combination since two compounds react to form a single new compound

For the fifth reaction:

`C_2H_2(g)+H_2(g)\rightarrow C__2H_6(g)(Hydrogenation)`

This is a hydrogenation reaction since it involves the addition of hydrogen to the given compound to produce a new compound.
