Question 2: label the following as synthesis, decomposition, combustion, single replacement, or double replacement

Question 2 Label The Following As Synthesis Decomposition Combustion Single Replacement Or Double Replacement class=

Sagot :

We are asked to label the reactions according to their type. We first define each type of reaction.

Synthesis: This type of reaction refers to one in which two or more reactants are linked to obtain a single compound as a product.

Decomposition: Here a reactant decomposes to form two or more products.

Single replacement: In this reaction, one of the reactants is in its natural form and during the reaction it displaces another linked element.

Double replacement: In this reaction, two linked elements swap places with each other.

Combustion reaction consist in the oxidation of a fuel with oxygen to form CO2 and water

Now, according to the definitions. The label for each reaction will be:

[tex]2KBr\rightarrow2K+Br_2[/tex]

We have one reactant that decomposes in two products, this is a decomposition reaction.

[tex]CH_4+O_2\rightarrow CO_2+H_2O[/tex]

We have a fuel that reacts with oxygen to form CO2 and water, this is a combustion reaction.

[tex]2Zn+2HCl\rightarrow H_2+2ZnCl[/tex]

In this reaction, Zn is in its natural state and takes the place of hydrogen. This is a single replacement reaction.

In summary, we have:

a. Decomposition reaction

b. Combustion reaction

c. Single replacement reaction
