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.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

the ratio of the conjugate base to the acid required to attain the desired ph.
