Question

Сумма коэффициентов в левой части уравнения равна: ? Cl2+NaOH—>NaClO+NaCl+H2O

Answer 1

Сумма коэффициентов в левой части уравнения равна: 3

1Cl₂+2NaOH—>NaClO+NaCl+H₂O

Answer 2

To find the sum of the coefficients on the left-hand side of the equation, you need to balance the chemical equation first. The balanced equation should have the same number of atoms of each element on both sides.

Let's balance the equation:

Cl2 + 2NaOH -> NaClO + NaCl + H2O

Now, the sum of coefficients on the left-hand side is:

1 + 2 = 3

So, the sum of the coefficients in the left-hand side of the balanced equation is 3.
