What is the product of the following chemical equation? C3H8(g) + 5O2(g) →
2 answers:
Answer: and
Explanation:
When a hydrocarbon burns in the presence of oxygen, it forms carbon dioxide and water and this a an example of combustion reaction.
Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. Reactants are written on left side of the arrow.
Products are defined as the substance which are formed at the end of the chemical reaction.Products are written on the right side of the arrow.
Thus the products are carbon dioxide and water.

Explanation:
Sodium formate is the conjugate base of formic acid.
Also,
for sodium formate is
Given that:
of formic acid =
And,
So,
Concentration = 0.35 M
HCOONa ⇒ Na⁺ + HCOO⁻
Consider the ICE take for the formate ion as:
HCOO⁻ + H₂O ⇄ HCOOH + OH⁻
At t=0 0.35 - -
At t =equilibrium (0.35-x) x x
The expression for dissociation constant of sodium formate is:
Solving for x, we get:
x = 0.44×10⁻⁵ M
pOH = -log[OH⁻] = -log(0.44×10⁻⁵) = 4.64
pH + pOH = 14
So,
<u>pH = 14 - 4.64 = 9.36</u>
