<h2>Let us explain about green house gases</h2>
Explanation:
Green house effect
It can be explained as :
- The sun emit radiations that consist of infra red rays , ultra violet rays and visible light .
- The infra red rays (responsible for heating ) when come from sun , it travels through atmosphere and reaches earth surface .
- On striking the earth surface , it gets reflected and reflected infra red ray has greater wavelength .
- Then this reflected rays moves back through atmosphere .
- On doing so , they encounter certain gas molecules like carbon dioxide , methane etc .
- This gases absorb these rays and do not let them to escape through them .
- As a result, they get trapped .
- As we have already mention that they cause heating effect , due to this property they raise the temperature of atmosphere leading global warming .

Explanation:
Given parameters:
pOH of RbOH = 6.32
Unknown:
Molarity of the base = ?
Solution:
The pH or pOH scale is used for expressing the level of acidity alkalinity of aqueous solutions.
pOH = -log[OH⁻]
we know the pOH to be 6.32
6.32 = -log[OH⁻]
[OH⁻] = inverse log₁₀(6.32)
[OH⁻] = 4.79 x 10⁻⁷moldm⁻³
