Answer:
2H₂S + SO₂ —> 2H₂O + 3S
Explanation:
From the question given above, the following equation were obtained:
H₂S + SO₂ —> H₂O + S
The equation can be balance as illustrated below:
H₂S + SO₂ —> H₂O + S
There are 2 atoms of O on the left side and 1 atom on the right side it can be balance by writing 2 before H₂O as shown below:
H₂S + SO₂ —> 2H₂O + S
There are 2 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 2 before H₂S as shown below:
2H₂S + SO₂ —> 2H₂O + S
There are 3 atoms of S on the left side and 1 atom on the right side. It can be balance by writing 3 before S as shown below:
2H₂S + SO₂ —> 2H₂O + 3S
Now, the equation is balanced.!
Answer:
r = 29.53 degrees
Explanation:
Given that,
Angle of incidence, 
We need to find the angle at which it will travel in the water. The refractive index of water is 1.33 and refractive index of air is 1. Using Snell's law as :
r is the angle of refraction
So, the ray will travel at an angle of 29.53 degrees in the water.
Students can make the force of two magnets stronger by putting the N and S pole right next to each other.
