Question

review iii
use the following chemical names to generate the chemical formulas for the following substances.
*when writing out formulas containing more than one of the same polyatomic ion, use parenthesis to separate the polyatomic ions from the rest of the formula. for example, nickel (ii) phosphate would be written as ni3(po4)2.
nitrogen monoxide
sodium hypochlorite
iron (iii) hydroxide

Explanation:

Nitrogen monoxide

• Step1: Analyze the elements

Nitrogen is \(N\) and monoxide indicates one oxygen atom (\(O\)).

• Step2: Write the formula

The formula is \(NO\).

Sodium hypochlorite

• Step1: Identify the ions

Sodium ion is \(Na^{+}\) and hypochlorite ion is \(ClO^{-}\).

• Step2: Balance the charges

Since the charges are \(+1\) and \(-1\), the formula is \(NaClO\).

Iron (III) hydroxide

• Step1: Determine the ions

Iron (III) ion is \(Fe^{3 +}\) and hydroxide ion is \(OH^{-}\).

• Step2: Balance the charges

To balance \(+3\) and \(-1\) charges, we need 3 \(OH^{-}\) ions. So the formula is \(Fe(OH)_{3}\).

Answer:

Nitrogen monoxide: \(NO\)
Sodium hypochlorite: \(NaClO\)
Iron (III) hydroxide: \(Fe(OH)_{3}\)
