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.

KCH₃COO

K₂CrO₄

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).

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
