f. cobalt(III) sulfate
Write the formula for each of the following:
a. sodium carbonate
b. nitrogen dioxide
c. aluminum nitrate
d. copper(I) nitride
e. potassium phosphate
f. cobalt(III) sulfate
Solution
Solution Steps
Step 1: Identify the Chemical Formulas
We need to write the chemical formulas for the given compounds. Each compound's name provides clues about its composition and the ratio of its constituent elements.
Step 2: Write the Formula for Sodium Carbonate
Sodium carbonate consists of sodium (Na) and carbonate (CO$_3$). Sodium has a charge of +1, and carbonate has a charge of -2. To balance the charges, we need two sodium ions for every carbonate ion.
Nitrogen dioxide consists of one nitrogen (N) atom and two oxygen (O) atoms.
\[
\text{Nitrogen dioxide: } \text{NO}_2
\]
Step 4: Write the Formula for Aluminum Nitrate
Aluminum nitrate consists of aluminum (Al) and nitrate (NO$_3$). Aluminum has a charge of +3, and nitrate has a charge of -1. To balance the charges, we need three nitrate ions for every aluminum ion.
