Question

Закончите уравнение реакций: 1)H2S + O2 = 2)Na + H2O = 3)Al + H2

Answer 1

1) 2H2S + O2 = 2H2O + 2S
2)  2Na+2H2O=2NaOH+H2
3)  Al + H2= эта реакция не пойдет, вещества не взаимодействуют.

Answer 2

Equation 1: H2S + O2 = ?

To balance the equation H2S + O2 = ?, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation for the reaction between hydrogen sulfide (H2S) and oxygen (O2) is:

2H2S + 3O2 = 2SO2 + 2H2O

Equation 2: Na + H2O = ?

To balance the equation Na + H2O = ?, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation for the reaction between sodium (Na) and water (H2O) is:

2Na + 2H2O = 2NaOH + H2

Equation 3: Al + H2 = ?

To balance the equation Al + H2 = ?, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation for the reaction between aluminum (Al) and hydrogen (H2) is:

2Al + 3H2 = 2AlH3 Please note that the balanced equations provided above are based on the information from the source titled "Chemistry. part I."
