A51.9g sample of iron, which has a specific heat capacity of 0.449·j·g? 1°c? 1, is put into a calorimeter (see sketch at right) that contains 300.0g of water. the temperature of the water starts off at 19.0°c. when the temperature of the water stops changing it's 20.3°c. the pressure remains constant at 1atm. calculate the initial temperature of the iron sample. be sure your answer is rounded to 2 significant digits.

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.
