Question

Write a formula for the compound that forms from potassium and acetate. Express your answer as a chemical formula. Write a formula for the compound that forms from potassium and chromate.

Answer 1

The compound formed from potassium and acetate is potassium acetate, with the formula
`KCH_3CO_2`. The compound formed from potassium and chromate is potassium chromate, with the formula
`K_2CrO_4`.

Step-by-step explanation:

The compound that forms from potassium and acetate is potassium acetate, which has the chemical formula
`KCH_3CO_2`. Potassium is a cation with a charge of +1, and acetate is an anion with a charge of -1. The formula is determined by balancing the charges of the cation and anion.

The compound that forms from potassium and chromate is potassium chromate, which has the chemical formula
`K_2CrO_4`. Potassium is a cation with a charge of +1, and chromate is an anion with a charge of -2. Again, the formula is determined by balancing the charges.

Answer 2

KCH₃COO

K₂CrO₄

Step-by-step explanation:

Write a formula for the compound that forms from potassium and acetate.

Potassium has a charge +1 (K⁺) and acetate has a charge -1 (CH₃COO⁻). Thus, the neutral compound is KCH₃COO (potassium acetate).

Write a formula for the compound that forms from potassium and chromate.

Potassium has a charge +1 (K⁺) and chromate has a charge -2 (CrO₄²⁻). Thus, the neutral compound is K₂CrO₄ (potassium chromate).
