Palmitic acid c16h32o2 is a dietary fat found in beef and butter. the caloric content of palmitic acid is typical of fats in general.
part a
write a balanced equation for the complete combustion of palmitic acid. use \rm h_2o(l) in the balanced chemical equation because the metabolism of these compounds produces liquid water.
express your answer as a chemical equation. identify all of the phases in your answer.

Explanation:

Combustion is a type of chemical reaction in which substance burns under the presence of oxygen or in other words reaction of hydrocarbon with oxygen to produce water and carbondioxide.

Palmitic acid when undergoes combustion it gives carbondioxide and water.

The balanced chemical  equation is given as:

According to stoichiometry, when 1 mol of palmitic acid reacts with 23 moles of oxygen to give 16 moles of carbondioxide and 12 moles of water.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
