A long chain of hydrocarbon bonded to cooh is a ________ acid.
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
A fatty acid is defined as a long chain of hydrocarbons that consists of a carboxylic group, that is, COOH group at the end of the chain.
General formula of a fatty acid is where n is mostly an even number in many cases.
Fatty acids are also known as aliphatic monocarboxylic acid.
For example, is the formula of stearic acid which is a fatty acid.
Thus, we can conclude that a long chain of hydrocarbon bonded to cooh is a fatty acid.

Answer:
2Li + F₂ → 2LiF
Explanation:
The reaction expression is given as:
Li + F₂ → LiF
We are to balance the expression. In that case, the number of atoms on both sides of the expression must be the same.
Let use a mathematical approach to solve this problem;
Assign variables a,b and c as the coefficients that will balance the expression:
aLi + bF₂ → cLiF
Conserving Li: a = c
F: 2b = c
let a = 1, c = 1 and b =
Multiply through by 2;
a = 2, b = 1 and c = 2
2Li + F₂ → 2LiF
