Vapour pressures of water above pure liquid water are 24, 529 and 760 torr respectively at 298, 363 and 373k. use these data to answer the questions
(i). change in chemical potential (in kj/mol) for the equilibrium h2o (liquid) = h2o (gas) at 298 k is
(a) 8.6 (b) – 3.8 (c) 7.87 (d) 3.72
(ii). aqueous solution of sodium chloride (χnaclz8isuvork5cyii= = 0.015) at 298 k is in equilibrium with a water vapour pressure (in torr) of
(a) 23.64 (b) 748.60
(c) 24.36 (d) negligible
(iii). average value of enthalpy of vaporization (in kj/mol) of water between 363 and 373 k is
(a) 42.50 (b) 4.080
(c) – 40.65 (d) -40.80

Compound with sulfer  is bright red 

Iimpact me by the one the yet but him.

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
