What is the formula for the compound formed between calcium and each of the following polyatomic ions? a. hydroxide b. chromate c. phosphate d. cyanide
Verified step by step guidance1
<insert step 1> Identify the charge of the calcium ion (Ca). Calcium is in group 2 of the periodic table, so it forms a Ca^{2+} ion.>
<insert step 2> Determine the charge of each polyatomic ion: hydroxide (OH^{-}), chromate (CrO_4^{2-}), phosphate (PO_4^{3-}), and cyanide (CN^{-}).>
<insert step 3> For each compound, balance the total positive and negative charges to ensure the compound is neutral.>
<insert step 4> Write the chemical formula for each compound by combining the calcium ion with the appropriate number of each polyatomic ion to achieve charge neutrality.>
<insert step 5> Review the formulas to ensure they reflect the correct stoichiometry based on the charges of the ions involved.>
