Question

Сa(OH)2 + HNO3 = Ca(NO3)2 + H2O чему равна сумма коэффициентов,помогите пожалуйста!

Answer 1

14 если уровнять и сложить все

Answer 2

Сa(OH)2 + 2HNO3 = Ca(NO3)2 + 2H2O
1+2+1+2=6
где ты тут нашла 14?

Answer 3

Chemical Equation Balancing

When balancing the chemical equation Ca(OH)2 + HNO3 = Ca(NO3)2 + H2O, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The balanced equation is:

Ca(OH)2 + 2HNO3 = Ca(NO3)2 + 2H2O

The sum of the coefficients in the balanced equation is 1 + 2 + 1 + 2, which equals 6.

This information is based on the chemical equation balancing principles
