Answer:
1121.08 millilitres of 0.223 M 
solution contains 0.250 moles of .
Explanation:
The formula for molarity of a solution:
Molarity = 0.223 M
n = 0.250 moles
Therefore, 1121.08 millilitres of 0.223 M solution contains 0.250 moles of .
That is called an unsaturated solution
Answer:
B
Explanation:
I don't know how to explain this but you get it
<span>Well, during the day, the water, as well as the surfaces surrounding the water, are heated by various thermodynamic processes: conduction, convection, radiation, etc. This in turn warms the water molecules in the lakes, streams, rivers, and oceans, thereby transferring heat (their kinetic energy) to the water molecules, which in turn receive that energy from the surrounding surfaces, or directly via radiation/insolation from the sun. When the water molecules attain enough energy, some of them attain enough energy to escape the surface of the liquid and enter the gas phase. Hence, as water is heated, more and more water molecules attain enough kinetic energy to enter the gas phase.</span>
Answer:
The correct option is: the precipitation of acidic compounds formed when components of air pollution interact with other components in the air.
Explanation:
<u>Acid rain</u> is a form of precipitation which is usually <u>acidic in nature</u>. The acidic nature of rain is due to the reaction of <u>water molecules with sulfur dioxide, carbon dioxide and nitrogen oxide present in the air, to produce acids.</u>
There are many adverse effects of acid rain, some of them are: effect on water bodies, forests, living organisms, corrosion of structures made of steel and weathering of buildings.
