When light travels from air into water,it slows down,causing it to change directions slightly
I am very sure that the answer is C. Hope it’s right :)
Answer:
See explanation
Explanation:
Now , we have the equation of the reaction as;
2H2S(g) + 302(g)------->2SO2(g) + 2H2O(g)
This equation shows that SO2 gas is produced in the process. Let us recall that this same SO2 gas is the anhydride of H2SO4. This means that it can dissolve in water to form H2SO4
So, when SO2 dissolve in rain droplets, then H2SO4 is formed thereby lowering the pH of rain water. This is acid rain.

Answer:
27.22dm³
Explanation:
Given parameters:
number of moles = 1 mole
temperature = 50°C, in K gives 50+273 =323K
Pressure = 98.6kpa in atm, gives 0.973atm
Unknown:
Volume of the gas = ?
Solution:
Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.
The ideal gas law is mathematically expressed as;
Pv = nRT
where P is the pressure of the gas
V is the volume
n is the number of moles
R is the gas constant
T is the temperature
Input the parameters and solve for V;
0.973 x V = 1 x 0.082 x 323
V = 27.22dm³
