Task 1.2h

1. Calculate the volumes of all of the gases involved in the reactions below if you start with 10cm³ of the first gas.
(a) CH₄(g) + 2O₂(g) --> CO₂(g) + 2H₂O(g)
(b) 2C₂H2(g) 5O₂(g) --> 4CO₂(g) + 2H₂O(g)
(c) N₂(g) + 3H₂(g) --> 2NH₃(g)
2. What volume of oxygen would be needed to convert 1dm³ of nitrogen monoxide, NO, to nitrogen dioxide, NO₂, if the temperature and pressure are kept constant?
3. What volume of oxygen at room temperature and pressure would be needed to completely burn 1 mole of butane, C₄H₁₀. (molar volume = 24.0 dm³mol^-1)
4. What would the final volume of gas produced in the reaction between 10cm3 of hydrogen and 10cm³ of hydrogen at 25^oC.
5. What is the total volume of gas produced at room temperature by the action of heat on 1g of silver nitrate?
2AgNO₃(s) --> 2Ag(s) + 2NO₂(g) + O₂(g)
