Which of the foods did you determine to be nutritious snacks?
answer: the freezing point of water will decrease by 7.44 k.
moles of sugar = 4 moles
mass of water = 1 kg
i = van't hoff factor of sugar = 1
the freezing point of water will decrease by 7.44 k.
b.casuality since scientists test everything out
cacl₂ is the chemical formula of calcium chloride, and its molar mass is 110.983 g/mol. it is an ionic compound comprising two chlorine anions and calcium cation. the bivalent calcium metal produces an ionic bond with two chlorine atoms. calcium chloride is found in nature in its hydrated forms. it also occurs in huge concentrations in natural brine from salt deposits and salt lakes.
calcium chloride is found as granules or flakes, as an odorless white powder. it exhibits a melting point of 782 degree celsius, density of 2.15 g/ml, and a high boiling point of over 1600 degree celsius.
