A student is asked to precipitate all of the silver ions from75.0 mL of a 0.100M solution of AgNO3by adding solid sodium chromate. Calculate the mass of solid sodium chromate the student should add to the AgNO3 solution.(Start by writing the chemical equation for the reaction the student will use to form the precipitate.)

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

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.
