radiometric dating methods
Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. It's often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.

<h3>
Answer:</h3>
Cl₂ + 2KI → 2KCI + I₂
<h3>
Explanation:</h3>
<u>We are given;</u>
Cl₂ + KI → KCI + I₂
We are required to balance the equation;
First we need to understand what is a balanced equation?
- A balanced equation is an equation that has equal number of atoms of each elements on the side of reactants and that of the products.
Second; Why is it important to balance chemical equations?
- Chemical equations are balanced so as to obey the law of conservation of mass.
- According to the law of conservation of mass, the mass of products should be equivalent to the mass of reactants.
How do we balance equations?
- We balance chemical equations by putting appropriate coefficients on the reactants and products.
Therefore, in this case;
- The balanced equation will be;
Cl₂ + 2KI → 2KCI + I₂
