Answer:
1) The temperature inside a diesel engine is high enough for two atmospheric gases nitrogen and oxygen to react and combine to form nitrogen oxides, NOₓ
At very high temperatures of above 1,300 °C, which are temperatures obtainable in the internal combusting chamber of a diesel engine under 100% load, air containing N₂ and O₂ is sucked in, and they combine to produce approximately 85% of the NOₓ pollutants produced from moving engine sources
2) a) N₂O contributes to the Greenhouse effect and therefore global warming
b) NO₂ contributes to the formation of smog and NO₂ combines with water to produce nitric acid which falls as acid rain, and causes irritation in the eyes and the respiratory system airways
c) Nitric oxide gas, NO, has the effect of depleting the Ozone layer which increases global warming and increased penetration of UVB

Uses Of Periscope
It is used in submarines to determine the distance of a torpedo and helps in deciding the right time for the attack.
It is used in a nuclear reactor to observe the chemical reactions that are taking place.
In military periscopes are used to observe from their hiding position. Hi

Answer:
1.6 L is the volume of NaOH that has reacted
Explanation:
The balanced reaction is:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
This is a neutralization reaction between a strong acid and a strong base. The products are the correspond salt and water.
We propose this rule of three:
1 mol of sulfuric acid needs 2 mol of NaOH to react to react
Then, 2.4 moles of H₂SO₄ will react with (2.4 . 2) / 1 = 4.8 moles of NaOH
As molarity is 3M, we can determine the volume of our solution
Molarity (M) = mol / volume(L) → Volume(L) = mol / Molarity
Volume(L) = 4.8 mol / 3 M = 1.6 L
