write the chemical formula for the compound formed by each pair of positive and negative ions.\nba²⁺ and no₃⁻:\nal³⁺ and co₃²⁻:\nk⁺ and po₄³⁻:
Answer
Explanation:
Step1: Balance charges for Ba²⁺ and NO₃⁻
To balance the +2 charge of Ba²⁺, we need 2 NO₃⁻ ions.
Step2: Write the chemical formula
The formula is Ba(NO₃)₂.
Step3: Balance charges for Al³⁺ and CO₃²⁻
To balance the +3 charge of Al³⁺ and - 2 charge of CO₃²⁻, we use the least - common multiple of 2 and 3. We need 2 Al³⁺ ions and 3 CO₃²⁻ ions.
Step4: Write the chemical formula
The formula is Al₂(CO₃)₃.
Step5: Balance charges for K⁺ and PO₄³⁻
To balance the +1 charge of K⁺ and - 3 charge of PO₄³⁻, we need 3 K⁺ ions.
Step6: Write the chemical formula
The formula is K₃PO₄.
Answer:
Ba(NO₃)₂ Al₂(CO₃)₃ K₃PO₄
