If 0.500 mol of each of the following solutes is dissolved in 2.0 l of water, which will cause the greatest increase in the boiling point of the solution? a. nacl b. ki c. co2 d. na2so4

D.

Explanation:

= change in boiling point

i= vant hoff factor = no of ions produced on complete dissociation

= boiling point constant

m= molality = =same for all solutes

1. For NaCl:

i=2

2. For ,

i=2

3. , i= 1 as it does not dissociate

4. For ,

i=3

Thus elevation in boiling point will be highest in solution.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
