Question

Складіть реакцію взаємодії СаО з водою, розставте коефіцієнти та у 50 відповідь вкажіть суму коефіцієнтів у реакції

Answer 1

CaO + H2O → Ca(OH)2

Сума коефіцієнтів = 1 + 1 + 1 = 3

Answer 2

Reaction of CaO with Water

The reaction of calcium oxide (CaO) with water (H2O) results in the formation of calcium hydroxide (Ca(OH)2). The balanced chemical equation for this reaction is as follows:

CaO + H2O → Ca(OH)2

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, we have one calcium atom (Ca) on the left side and one on the right side, one oxygen atom (O) on the left side and two on the right side, and two hydrogen atoms (H) on the left side and two on the right side. Therefore, the equation is already balanced.

The coefficients in the balanced equation represent the number of moles of each substance involved in the reaction. In this case, the coefficient of CaO is 1, the coefficient of H2O is 1, and the coefficient of Ca(OH)2 is also 1.

Sum of Coefficients in the Reaction

To find the sum of the coefficients in the reaction, we add up the coefficients of all the substances involved. In this case, the sum of the coefficients is:

1 (CaO) + 1 (H2O) + 1 (Ca(OH)2) = 3

Therefore, the sum of the coefficients in the reaction is 3.

Please note that the reaction mentioned above is for calcium oxide (CaO) and water (H2O), not for aluminum hydroxide (Al(OH)3) and sulfuric acid (H2SO4) as mentioned in the search snippet. If you have any further questions, feel free to ask!
