Answer
Explanation:
Step1: Determine ions in potassium chromate
Potassium has a +1 charge ($K^+$) and chromate ion ($CrO_4^{2 - }$) has a - 2 charge.
Step2: Balance charges
To balance the charges, we need 2 potassium ions for 1 chromate ion.
Step3: Write chemical formula for potassium chromate
$K_2CrO_4$
Step4: Determine ions in copper(I) fluoride
Copper(I) has a +1 charge ($Cu^+$) and fluoride ion ($F^-$) has a - 1 charge.
Step5: Write chemical formula for copper(I) fluoride
Since the charges are equal in magnitude and opposite in sign, the chemical formula is $CuF$.
Answer:
Potassium chromate: $K_2CrO_4$ Copper(I) fluoride: $CuF$
