The primary sources of acidity in acid rain are the gases SO and NO So, the correct option is (c) SO and NO
A chemical process that starts when gases like sulphur dioxide and nitrogen oxides are discharged into the atmosphere leads to acid rain. These substances have the ability to ascend very far into the sky, where they combine and react with oxygen, water, and other chemicals to produce acid rain, an additional form of acidic pollution.
Acidic particles corrode metal and hasten the deterioration of paint and stone. Power plants are the primary sources of SO . Burning fossil fuels produces nitrogen dioxide (like gasoline). Cars, lorries, and power plants are the biggest producers of NO.
Therefore, The primary sources of the acidity in acid rain are the gases SO and NO.So, the correct option is (c) SO and NO

Answer: give me more of an explaination
Explanation:
Answer:
Methane
Explanation:
Methane is a synthetic compound with the substance recipe CH4. It is a gathering 14 hydride and the most straightforward alkane, and is the principle constituent of petroleum gas
Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
Internal energy= (- heat evolved by the system) + Work done by the system
ΔU = -Q+W
W = - PΔV
P= pressure
ΔV =difference in volume
Given,
V1 = 10 L
V2 = 90 L
∴ΔV = V2-V1 = 90-10 = 80 L
P = 1 atm
∴W = - ( 1× 80)
= -80 kJ
Heat evolved by the system = 90 kJ
∴Δ U= - 90 kJ - 80 kJ
= - 170 kJ
Thus, Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
NOTE : here work done by the system is considered negative and also heat evolved by the system is taken -Ve.
