Question:

In the decomposition reaction of aluminum chlorite, 75.0 grams is heated to produce oxygen and indium chloride?

Write the balanced equation for the reaction and find the mole ratios of the reactants and products required to solve any stoichiometric problemFind the volume of Oxygen in liters formed at 25C if the gas is collected over mercury and under a pressure of 670 torr

Answer:

Your car is probably the best example pneumatic (tires) pneumatic and hydraulic (shocks) hydraulic (power steering or brakes)
Pneumatic (bike pump), Hydraulic (log splitter)
Al(ClO2)3 - AlCl3 3O2 use molar mass to find moles Al: 75.0 grams 229.34 g/mol 0.3270 moles of Al(ClO2)3 using the equation: Al(ClO2)3 - AlCl3 3O2 0.3270 moles of Al(ClO2)3 produces 3 X's as many moles of O2+ 0.981 moles of O2 find litres+ PV nRT (670Torr)V 0.981 mol (62.4 Torr-Litres/mol-K)(298Kelvin) V 27.23 litres which in this 3 sig fig problem rounds off to: your answer 27.2 litres of oxygen
