For the following following balance the equation and indicate the correct coefficients used. when Methanol (CH3OH) burns in oxygen, carbon dioxide, water and heat are produced.

CH₃OH + 1.5 O₂ ⇒ CO₂ + 2 H₂O

Explanation:

Let's consider the unbalanced chemical equation for the complete combustion of methanol.

CH₃OH + O₂ ⇒ CO₂ + H₂O

We will balance it using the trial and error method.

First, we will balance H atoms by multiplying H₂O by 2.

CH₃OH + O₂ ⇒ CO₂ + 2 H₂O

Finally, we get the balanced equation by multiplying O₂ by 1.5.

CH₃OH + 1.5 O₂ ⇒ CO₂ + 2 H₂O

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
