Reducing the emissions of which gas will lead to reducing the greenhouse effect? A) oxygen B) nitrogen C) argon D) carbon dioxid
2 answers:
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
Green house gases are defined as the gases that absorb heat and also emit radiant heat with infrared radiation. These gases contributes to the green house effect. The heat radiated from these gases get trapped in the Earth atmosphere and it then results in the rise of temperature of the Earth surface.
There are 4 main gases that are known as green house gases. These are carbon dioxide , methane
, nitrous oxide
and ozone
. These gases also include chlorofluorocarbons also known as CFCs.
The reduction of any these gases will result in the reduction of greenhouse gases.
Thus, the correct answer is Option D.

This is an incomplete question, here is a complete question.
The Henry's law constant for oxygen dissolved in water is 4.34 × 10⁹ g/L.Pa at 25⁰C.If the partial pressure of oxygen in air is 0.2 atm, under atmospheric conditions, calculate the molar concentration of oxygen in air-saturated and oxygen saturated water.
Answer : The molar concentration of oxygen is,
Explanation :
As we know that,
where,
= molar solubility of
= ?
= partial pressure of
= 0.2 atm = 1.97×10⁻⁶ Pa
= Henry's law constant = 4.34 × 10⁹ g/L.Pa
Now put all the given values in the above formula, we get:
Now we have to molar concentration of oxygen.
Molar concentration of oxygen =
Therefore, the molar concentration of oxygen is,
