Answer:
atmosphere and hydrosphere
Explanation:
The polar ice caps are part of the cryosphere, which in turn is part of the hydrosphere, which is the sphere that contains all the waters on the planet. The atmosphere has been experiencing changes, with the increase of greenhouse gasses being the most noticeable and most important one. These gasses have contributed to the rise of the global temperatures. As the temperatures have been rising, the ice started to melt, thus it was influenced by the atmosphere, and as it is melting it is getting into the ocean water, thus increasing them. The more water there is in liquid form, and the higher the temperatures are, the higher the evaporation will be, so there will an increase in the amount of water vapor in the atmosphere. This is a nice example of the interaction between these two spheres.
The pH of the solution is obtained to be 9.67.
<h3>What is a buffer?</h3>
A buffer is a solution that serves to militate against changes in acidity or alkalinity. The buffer is often made of a solution of a strong acid and its salt or a weak base and its salt.
Now we have the that;
Number of moles of base = 250 /1000 * 0.80 = 0.2 moles
Number of moles of salt = 150/1000 * 0.50 = 0.075 moles
Total volume of the solution = 250 + 150 = 400 mL or 0.4 L
Molarity of the base = 0.2 moles/0.4 L = 0.5 M
Molarity of the salt = 0.075 moles/ 0.4 L = 0.1875 M
pKb = - log( 1.8 x 10^-5) = 4.74
pOH = pKb + log [salt/base]
pOH = 4.74 + log (0.1875/ 0.5)
pOH = 4.33
pH = 14 - 4.33
pH = 9.67
The pH of the solution is obtained to be 9.67.

Explanation:
Ammonia is a versatile laundry additive, vanquishing stains and dissolving grease as well as whitening whites and softening your bath towels. But its fumes and dangerous reactions when mixed with other household cleaners mean you need to be careful when using it.
