Based on the name, which substance is a covalent compound?

Sindrei [870]

Answer:

dinitrogen pentoxide

Explanation:

Based on the research, dinitrogen pentoxide is a chemical compound containing only nitrogen and oxygen which is both nonmetal. When two nonmetals or two negatively charged atoms try to form bonds, they always form covalent bonds. Hence, Dinitrogen Pentoxide is not ionic - it is covalent.

Identify the single displacement reaction. C4H12 + 7O2 ⟶ 6H2O + 4CO2 2H2 + O2 ⟶ 2H2O Al2S3 ⟶ 2Al + 3S Cl2 + 2KBr ⟶ 2KCl + Br2

Varvara68 [4.7K]

Answer:- $Cl_2+2KBr\rightarrow 2KCl+Br_2$

Explanations:- The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

$A+B\rightarrow AB$

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

$AB\rightarrow A+B$

In general, a single displacement reaction looks like:

$AB+C\rightarrow AC+B$

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, $Cl_2+2KBr\rightarrow 2KCl+Br_2$ .
