Write a balanced chemical equation based on the following description: butanoic acid, C₃H₇COOH(l) burns in air

The balanced chemical equation when butanoic acid burns in air would be

Butanoic acid goes by the formula C₃H₇COOH

Air is largely made of oxygen gas. Hence, when something burns in air, it is essentially burning in oxygen gas (O2).

Hydrocarbons generally burn in air to produce carbon dioxide and water respectively.

Therefore the reaction of butanoic acid and oxygen can be represented in the form of a chemical equation as:

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.

The balanced reaction for combustion of butanoic acid is:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
