Moles, masses and volume calculations

 For each of the following write a balanced chemical reaction and calculate the masses or volumes required using mole calculations:

1)     Look at the following reaction:

                       2Al(s)    +          3FeO(s)                    Al2O3(s)            +          3Fe(s)

        What mass of iron can be produced when 108 g of aluminium is used?

 

2)     Iron is produced in the blast furnace from iron (III) oxide by

                       Fe2O3(s)              +          3CO(g)                         2Fe(s)               +          3CO2(g)

                       What is the mass of iron that can be produced from 640g of iron(III) oxide.

3)      1.24g of sodium oxide reacted with excess hydrochloric acid.  What mass of salt was made?

4)      7.8g of aluminium hydroxide reacted with nitric acid.  What is the minimum mass of nitric acid required to react with all of the aluminium hydroxide?

5)      1.4g of lithium was dropped into an excess of sulphuric acid.  What volume of Hydrogen is made (in dm3)?

6)      5.52g of potassium carbonate reacted with excess hydrochloric acid.

 

     a)  What mass of salt was made?

     b)  What volume of carbon dioxide was produced (in cm3)?

     c)  What volume of water vapour was produced (in cm3)?

     d)  If the water vapour was collected and condensed, what would be its mass?

 

7)      1.2dm3 of pentane was completely burnt in excess oxygen.

 

     a)  What volume of carbon dioxide was produced (in cm3)?

     b)  What volume of water vapour was produced (in dm3)?

     c)  If the water vapour was collected and condensed, what would be its mass?
