Carbon dioxide is a gas having chemical formula 
, a gas which exhaled by humans and inhaled by plants. It is also emitted from the sources such as cement production and combustion of fossil fuels. It is also known as greenhouse gas associated with acidification of ocean.
Carbon dioxide with other gases acts like a blanket of Earth which absorbs infrared radiations emitted from the sun and thus, preventing the escaping of these rays into the outer space which results in the gradual heating of Earth's surface and atmosphere i.e. increase in temperature of Earth. This process is known as Global Warming.
Hence, carbon dioxide is responsible for the increase in warming of the atmosphere i.e. option (D).
Answer: pH = 3.15
Explanation: Solved in the attached picture.
Q=mcθ
m= 0.0775 kg
c= 4184 J·kg−1·K−1.
θ= T(final) - T(initial), 95-(-8)
Q=33398.78 J so kJ divide 1000
= 33.39878 kJ
