1.35 m solution NaOCl in water is prepared. What is the mole fraction of the NaOCl?

Chemistry
1 answer:
MAXImum [283]2 years ago
4 0

Answer:

NaOCl + H2O → HOCl + NaOH

so the mole fraction is = moles of NaOCl/(moles of NaOCl+moles of H2O)

so for 1.35 NaOCl it will require 1.35 moleof H2O

mole fraction = 1.35/(1.35+1.35)

mole fraction = 1/2 =0.5

is it correct i d ek but i tried :)

Ice floats on water. For most other substances, however, the solid sinks in the liquid.
svetoff [14.1K]

Answer:The solid is less dense than the liquid

Explanation:

Ice is less dense than water because of the crevices or spaces in the lattice structure of ice. Liquid water has a much greater density than solid water because its molecules are more compactly packed than in ice. Ice has large spaces between the hydrogen bonded water molecules hence less density than the liquid. Being less dense than !liquid water, it floats on water.

31. calculate the amount of energy released as heat by the freezing of 13.3 g of a liquid substance, given that the substance ha
spin [16.1K]

From the calculations, the heat of fusion of the substance is 0.73 kJ

<h3>What is is the heat of freezing?</h3>

The heat of freezing is the energy released when the substance is converted from liquid to solid.

Now we know that the molar mass of the substance is 82.9 g/mol  hence the number of moles of the substance is;  13.3 g /82.9 g/mol  = 0.16 moles

Now the heat of fusion shall be;

H = 4.60 kj/mol * 0.16 moles

H = 0.73 kJ
