Answer:
(C) Mass of KCl(s), mass of H20, initial temperature of the water, and final temperature of the solution
Explanation:
molar enthalpy of solution of KCl(s) is heat evolved or absorbed when one mole of KCl is dissolved in water to make pure solution . The heat evolved or absorbed can be calculated by the following relation.
Q = msΔt where m is mass of solution or water , s is specific heat and Δt is change in temperature of water .
So data required is mass of water or solution , initial and final temperature of solution , specific heat of water is known .
Now to know molar heat , we require mass of solute or KCl dissolved to know heat heat absorbed or evolved by dissolution of one mole of solute .
The Lithosphere ("rock sphere") is the ground you are standing on and the whole inside of Earth.
The Hydrosphere ("water sphere") includes all of the rivers, lakes and oceans of Earth.
The Cryosphere ("icy cold sphere") is the frozen part of Earth: the glaciers, icebergs at sea, and the huge icecaps in Greenland and Antarctica.
The Biosphere ("Life sphere") includes all living things: the trees in the park, the birds in the air, the fly on your wall, the viruses that make you sick, your pets, and even you and all your friends!
The Atmosphere ("Air Sphere") is the envelope of air that surrounds the whole Earth.
The Exo- or Celestial Sphere ("Outside or heavenly sphere") includes the whole universe beyond the top of the atmosphere--the Sun, Moon, and stars, as well as the asteroids and the little bits of dust that make meteors when they hit the atmosphere.
