Fish in a frozen lake can survive throughout the winter months due partially to the fact that lakes don't freeze solid. Fresh water has a density
of 1.00 g/cm3. A piece of ice has a mass of 57g and a volume of 62 cm3.
Give the density of the piece of ice (use the density formula d = m/V) and
explain what will happen to it in the lake.

How does litmus paper indicate an acid?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
