Question

Расставьте козффишиенты в уравнении реакции и посчитайте их сумму: H2S+O2=S+H2O​

Answer 1

Объяснение:

2H2S+O2=2S+2H2O

ответ: 7

Answer 2

To balance the chemical equation: H2S + O2 = S + H2O, we need to ensure that the number of atoms of each element is equal on both sides of the equation. Here's how the balanced equation looks:

2 H2S + 3 O2 = 2 S + 2 H2O

Now, let's calculate the sum of the coefficients:

Sum of coefficients = 2 + 3 + 2 + 2 = 9

So, the sum of the coefficients in the balanced equation is 9.
