the mass of ice taken = 10 g
the mass of water = 250 g
initial temperature of water = 20 C
the final temperature of water = 16. 8 C
specific heat of water = 4.18 J/g*K
the heat absorbed by ice to melt = heat loss by water
heat loss by water = mass X specific heat of water X change in temperature
heat loss by water = 250 X 4.18 X (20-16.8) = 3344 Joules
heat gained by ice = 3344 J
heat gained by ice = enthalpy of fusion X moles of ice
moles of ice = mass / molar mass = 10 / 18 = 0.56 moles
enthalpy of fusion = 3344 / 0.56 = 5971.43 J / mole

This <u>heterogeneous </u>mixture is a suspension of oil and vinegar
A mixture is a physical combination of two or more substances and each of these substances preserves its identity and form in the mixture.
A homogeneous mixture is a mixture in which is one substance thoroughly dissolves in the other and its composition is uniform throughout the solution. e.g salt and water.
A heterogeneous mixture is one in the two substances form two layers and their composition varies throughout the mixture.
From the given information, the mixture of oil and vinegar is an example of a heterogeneous mixture.
