<u>Answer:</u> The given reaction represents a combustion reaction.

<u>Explanation:</u>

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

Combination reaction is defined as the reaction in which two or more smaller substances combine to form a single large substance.

A+B\rightarrow AB

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

C_xH_y+O_2\rightarrow CO_2+H_2O

A double displacement reaction is defined as the reaction in which exchange of ions takes place.

AB+CD\rightarrow AD+CB

A single displacement reaction is defined as the reaction in which a more reactive element displaces a less reactive element from its chemical reaction.  The reactivity of metal is determined by a series known as reactivity series.

AB+C\rightarrow CB+A

Metal C is more reactive than metal A.

For the given chemical reaction:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

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

What causes some aqueous solutions to have a low PH?
noname [10]
<span> Low pH means the solution is acidic; if the solution is acidic, that means that there are hydronium ions in solution (H3O+). For example, hydrochloric acid dissolves into H+ ions and Cl- ions, and the H+ ions rreact with water like this:
H+ + H2O --> H3O+

If you want to get mathematical, pH is defined as the negative log of the concentration of hydronium ions.
Thus, if there are a lot of hydronium ions, the solution will have a low, or acidic, pH.  Hope this helps^-^</span>

45) George is making spaghetti for dinner. He places 4.01 kg of water in a pan and brings it to a boil.
lesya692 [45]
On adding salt.....The boiling temperature increases.....

So ∆t= KB * molality
=O.52*(58/58)/4
= O.52*1/4
= 0.13
So increase is 100+.13=100.13°c
