kci + iz
what the balance?

Cl₂ + 2KI → 2KCI + I₂

Explanation:

We are given;

Unbalanced equation;

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

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
