Answer 1

Answer:

Use of Parenthesis

When more than one polyatomic ion is required, parenthesis are used to enclose the ion with the subscript going outside the parenthesis. For example, the very first formula used is Fe(NO3)2. This means that two NO3¯ are involved in the compound.

Answer 2

Answer:

Only one polyatomic ion

Explanation:

Na (Sodium) has a radical of +1 and OH (Hydroxide) has a radical of -1

The Valencies of both are 1.

When reacting, the valencies are exchanged.

Then the formula will be Na1(OH)1 which is equal NaOH.
