Question

Расставить коофиценты, вычислить их сумму H2S +O2 -> s+H2o

Answer 1

2H2S + O2 = 2S +2H2O
С ТОЙ СТОРОНЫ - 6, И СТОЙ СТОРОНЫ - 6

Answer 2

To balance the chemical equation H2S + O2 -> S + H2O, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's proceed with balancing the equation step by step:

1. Balance the hydrogen (H) atoms: There are 2 hydrogen atoms on the left (H2S) and 2 hydrogen atoms on the right (H2O). The hydrogen atoms are already balanced.

2. Balance the oxygen (O) atoms: There is 1 oxygen atom on the left (O2) and 2 oxygen atoms on the right (S + H2O). To balance the oxygen atoms, we need to add a coefficient to O2. Since 2 molecules of O2 contain a total of 4 oxygen atoms, we need to add a coefficient of 2 in front of O2.

The balanced chemical equation is now: H2S + 2 O2 -> S + H2O

Next, let's calculate the coefficients for the given reaction and then find their sum:

• Coefficient of H2S: 1 (already balanced)
• Coefficient of O2: 2 (already balanced)
• Coefficient of S: 1 (already balanced)
• Coefficient of H2O: 2 (already balanced)

The sum of the coefficients is: 1 + 2 + 1 + 2 = 6

So, the sum of the coefficients in the balanced chemical equation is 6.
