Answer from: AM28

1 - Synthesis

2 - Combustion

Chemical Reaction A is synthesis because both elements have synthesized into one, HCl.

Chemical Reaction B is combustion due to the fact that the products are carbon dioxide and water. A combustion reaction is a reaction that produces these products.

Hope this helps!

Answer from: Playboycxm

The correct answer is Synthesis and Combustion reaction.

Explanation:

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

$\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O$

Decomposition reaction is defined as the chemical reaction in which a single substance breaks down into two or more simpler substances.

$AB\rightarrow A+B$

Double displacement reaction is defined as the chemical reaction in which exchange of ions takes place.

$AB+CD\rightarrow AD+CB$

Single displacement reaction is defined as the chemical reaction in which more reactive element displaces a less reactive element from its chemical reaction.

$AB+C\rightarrow CB+A$

Synthesis reaction is defined as the chemical reaction in which substances combine in their elemental state to form a single compound.

$A+B\rightarrow AB$

For A: $H_2+Cl_2\rightarrow 2HCl$

This reaction is considered as a synthesis reaction because hydrogen gas and chlorine gas are combining in their elemental states to produce hydrochloric acid molecule.

For B: $CH_4+2O_2\rightarrow CO_2+2H_2O$

This reaction is considered as a combustion reaction because methane gas is reacting with oxygen gas to produce carbon dioxide gas and water molecule.

Thus, the correct answer is Synthesis and combustion reaction.

Answer from: Quest

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
