Question

SO2 + O2 = SO3 ОБЪЯСНИТЕ РАССТАНОВКУ КОЭФФИЦЕНТОВ

Answer 1

2so2+o2=2SO3 коэффициент перед SO3 стоит, потому что нужно уравнять кислород (в левой части его больше) коэффициент перед so2 стоит, потому что в правой части уравнения 2 S и их надо уравнять

Answer 2

Это окислительно-восстановительная реакция.
S - восстановитель, т.к. ст.о. повышается от +4 до +6
O - окислитель т.к. ст. о понижается с 0 до -2
Составляем баланс:
S^+4  -2e-->  S^+6  | 2 окисление  
O2^0  +4e--> 2O^-2 | 1 восстановление 

2SO2 + O2 = 2SO3

Answer 3

Balancing the Equation SO2 + O2 = SO3

To balance the chemical equation SO2 + O2 = SO3, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's how we can balance it step by step:

1. Start by counting the number of atoms for each element on both sides of the equation: - Sulfur (S): 1 atom on the left, 1 atom on the right. - Oxygen (O): 2 atoms from SO2 on the left, 2 atoms from O2 on the left, and 3 atoms from SO3 on the right.

2. Begin by balancing the sulfur atoms: - Since there is 1 sulfur atom on both sides, we don't need to make any changes.

3. Next, balance the oxygen atoms: - There are 2 oxygen atoms from SO2 on the left and 2 oxygen atoms from O2 on the left, totaling 4 oxygen atoms on the left. - On the right, there are 3 oxygen atoms from SO3.

4. To balance the oxygen atoms, we need to add a coefficient in front of the oxygen molecules. Let's start by placing a coefficient of 2 in front of SO3: - The equation becomes: SO2 + O2 = 2SO3.

5. Now, let's count the number of oxygen atoms again: - On the left, there are 2 oxygen atoms from SO2 and 2 oxygen atoms from O2, totaling 4 oxygen atoms. - On the right, there are 6 oxygen atoms from 2SO3.

6. To balance the oxygen atoms, we need to add a coefficient in front of the oxygen molecules on the left side. Let's place a coefficient of 3 in front of O2: - The balanced equation is: SO2 + 3O2 = 2SO3.

Now, the equation is balanced, with 1 sulfur atom and 6 oxygen atoms on both sides.

Final balanced equation: SO2 + 3O2 = 2SO3.
