identify the ion ratios needed to form neutral compounds from the ions below. the metal ion (cation) is listed first, and the nonmetal ion (anion) is listed second. make sure to give each ratio in its most simplified form.\nna⁺:br⁻ = 1:\nal³⁺:cl⁻ = 1:\nmg²⁺:o²⁻ = 1:\nal³⁺:o²⁻ = 2:\ndone
Answer
Explanation:
Step1: Determine ratio for Na⁺ and Br⁻
The charges of Na⁺ and Br⁻ are +1 and - 1 respectively. To form a neutral compound, the ratio is 1:1.
Step2: Determine ratio for Al³⁺ and Cl⁻
Al³⁺ has a charge of +3 and Cl⁻ has a charge of -1. To balance the charges, we need 3 Cl⁻ for 1 Al³⁺, so the ratio is 1:3.
Step3: Determine ratio for Mg²⁺ and O²⁻
Mg²⁺ has a charge of +2 and O²⁻ has a charge of -2. The ratio for a neutral compound is 1:1.
Step4: Determine ratio for Al³⁺ and O²⁻
Al³⁺ has a charge of +3 and O²⁻ has a charge of -2. The least - common multiple of 3 and 2 is 6. So we need 2 Al³⁺ (total charge = +6) and 3 O²⁻ (total charge=-6) for a neutral compound. Given the ratio as 2:?, the missing number is 3.
