The concentration of silver ion in the final solution is calculated using dilution principles.

What is the molecular equation for the reaction of hydrobromic acid with potassium hydroxide?

The molecular equation is HBr + KOH → KBr + H2O.

What is the volume of gas in a balloon that initially has a pressure of 1.00 atm and is cooled to 5.0°C, resulting in a pressure of 0.750 atm?

The volume can be calculated using the combined gas law.

What is an exception to the generalization that most chloride salts are soluble?
