3.(c) What would be the volume of steam produced at the same time if measured at 760 mmHg pressure and 273°C?
-
4.What volume of oxygen is required to completely burn a mixture of 224 cm³ of methane and 112 cm³ of hydrogen at S.T.P. to produce steam and carbon dioxide? If the steam formed is condensed to water, find the mass of water so formed.
-
5.Hydrogen is generated by the action of steam with heated magnesium. Calculate the mass of magnesium which will produce just sufficient hydrogen to combine with all the oxygen that can be obtained by the complete decomposition of 24.5 g of KClO₃.
