- It has an impact on ocean temperatures, the speed and strength of ocean currents together with the health of coastal fisheries. Its events occur irregularly at two- to seven-year intervals.
Answer:
MgI₂, MgO, PbI₄, PbO₂
Explanation:
For an ionic compound to be formed, it must be neutral, that is the total positive charge must be equal to the total negative charge.
Mg²⁺ and I⁻: The neutral ionic compound requires 1 Mg²⁺ and 2 I⁻ and the resulting empirical formula is MgI₂.
Mg²⁺ and O²⁻: The neutral ionic compound requires 1 Mg²⁺ and 1 O²⁻ and the resulting empirical formula is MgO.
Pb⁴⁺ and I⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 4 I⁻ and the resulting empirical formula is PbI₄.
Pb⁴⁺ and O²⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 2 O²⁻ and the resulting empirical formula is PbO₂.
