Question

Вкажіть суму коефіцієнтів у реакції хром 3 гідроксиду та нітратної кислоти

Answer 1

Ответ:

Cr(OH)3 + 3 HNO3 → 3 H2O + Cr(NO3)3

Сума коефіцієнтів = 8

Answer 2

Coefficients in the Reaction of Chromium(III) Hydroxide and Nitric Acid

The balanced chemical equation for the reaction between chromium(III) hydroxide and nitric acid is as follows:

Cr(OH)3(s) + 3HNO3(aq) → Cr(NO3)3(aq) + 3H2O(l)

Here, the coefficients in the balanced chemical equation are as follows: - The coefficient of chromium(III) hydroxide (Cr(OH)3) is 1. - The coefficient of nitric acid (HNO3) is 3. - The coefficient of chromium(III) nitrate (Cr(NO3)3) is 1. - The coefficient of water (H2O) is 3.

This means that one mole of chromium(III) hydroxide reacts with three moles of nitric acid to produce one mole of chromium(III) nitrate and three moles of water.
