a 75.5 g sample of an unknown solid is heated to 62.2 degrees celcius and placed into a calorimeter containing 96.9g of water at 20 degrees celcius. if the final temperature of the solid sample and water is 31.1 degrees celcius, what is the specific heat of the solid

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

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.
