Identify the missing coefficient in the balanced equation and classify the type of reaction. c2h5oh + 3o2 ⟶ + 3h2o 2; neutralization 2; combustion 3; neutralization 3; combustion

C2H5OH(l) +3O2(g) → 2CO2(g) + 2H2O(l)

it is combustion reaction and heat is also produced.

Explanation:

This is oxidation reduction reaction which is also called redox reaction.

C2H5OH  is reducing agent while O2 is oxidizing agent.

Chemical equation:

C2H5OH + O2 → CO2 + H2O

Now we will balance the equation. In given chemical equation two carbon atoms on the left side and one carbon atom on the right side. While six hydrogen atoms are present on the left and just two hydrogen on right side. We will write coefficient two with carbon dioxide and and three with water molecules.

C2H5OH + O2 → 2CO2 + 3H2O

now we will balance the oxygen atoms. we can see there are three oxygen atoms on the left and seven on right side. we will write coefficient three with oxygen on left and equation becomes balance.

C2H5OH + 3O2 → 2CO2 + 3H2O

Complete chemical equation with physical states:

C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

explanation: no but i do not usually comment

wher is the rest of the question
