### Question:Which of the following polyatomic ions can form a balanced compound in a 1:1 ratio with a single ion of calcium? Select all that apply.- Nitrile- Dihydrogen phosphate- Phosphate- Arsenate- Sulfate- Hydrogen phosphate### Explanation:The question asks which polyatomic ions can combine with calcium ions (Ca²⁺) to form a balanced compound where the ratio of calcium ions to the selected polyatomic ions is 1:1. Calcium typically has a charge of +2. Look for polyatomic ions with a -2 charge to achieve a 1:1 stoichiometric ratio.

Given element is Calcium.Calcium forms positive ion which has charge +2.

14 In an alien world, a different periodic table exists. It is organized similar to the periodic table in our world, just smaller. The first group contains the alkali metals, the second group the alkaline earth metals, there are a few transition metals, and then some non-metals. The periodic table is shown below in picture form, and a table is given with molar masses and common ionic charges. Also in the table is a list of common ion groups (similar to carbonate, nitrate, etc. in our world.)
