Answer:
Explanation:
Carbon sink is basically anything that absorbs carbon from the atmosphere. Particularly, the soil, trees, plants and the ocean absorb the most carbon, which helps with greenhouse emission.
I believe it is b. I hope this helps you
Osmolarity=osmole of the solute/litres of the solution
ionic equation for dissociation of CaCl2 is
CaCl2--->Ca2+ +2Cl-
total osmoles for reaction are 1(Ca2+) + 2(Cl-)= 3 osmoles
therefore
0.50 moles of CaCl2 x 3 osmoles/ 1mole of CaCl2 = 1.5osmoles
osmolarity=1.5 /1.0 L=1.5 osmol/l
