Write the Equation for the dissolution of Sr2NO3 in water. How many moles of strontium ions and nitrate ions are produced by dissolving 0.5 mol of strontium nitrate?
Balance the equation and answer in terms of moles.Chlorine gas can be produced commercially by passing an electric current through a concentrated solution of sodium chloride (brine).
In the spring of 1996 five tank cars containing propane (molar mass = 44.09 g/mol) derailed in Weyauwega, WI forcing evacuation of the town for over a week. Residents within a square mile of the accident site were unable to return to their homes f..
