2. How can you determine if an acid is binary when given the
formula?

Explanation:

Binary acids are molecular compounds that consists of two components.

The components are Hydrogen and a non metal. Examples of binary acids include; HCl, HF etc.

The way to identify binary acids is to spot the hydrogen and the non metal.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
