Answer:
Vapor pressure for solution is 22.4 Torr
Explanation:
P° → Vapor pressure of pure solvent
P' → Vapor pressure of solution
Formula for lowering vapor pressure is: P° - P' = P° . Xm
Xm is the mole fraction. Let's determine it:
0.220 mol of solute + 3.70 mol of water = 3.92 total moles
Mole fraction for solute → 0.220 / 3.92 = 0.056
23.8 Torr - P' = 23.8 Torr . 0.056
P' = - ( 23.8 Torr . 0.056 - 23.8 Torr ) → 22.4 Torr
<span>CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair.</span>
Solids— have tightly packed molecules, structured shape
Liquid— have no definite shape and the molecules are not tightly packed like a solid, they are a lot more loose.
Gas— No structure at all, molecules are free flowing
Sorry I couldn’t be a better help.. but I hope this gives you a bit of an idea :)
BeCl2 = Beryllium Chloride
2H2O = 2 molecules of H2O (water)
LiNO2 = Lithium Nitrate
H2O = water
Explanation:
2H2(g) + O2(g) → 2H2O(l ) Chemical equations give the following information about chemical reactions. Chemical equations show the formulas for the substances that take part in the reaction.
