Write the balanced equation for each of the chemical reactions:

a) Solid sodium is added to water and reacts to form a solution of sodium hydroxide.

b) Solid cobalt (III) oxide reacts with carbon to produce cobalt metal and carbon dioxide.

c) The fermentation of sugar, C12H22O11, in which aqueous sugar reacts with water to form aqueous ethanol, C2h5OH, and carbon dioxide gas.

d) Solid metallic aluminum reacts with aqueous hydrochloric acid to produce aqueous aluminum chloride and hydrogen gas.

Solutions

Expert Solution

1) Balanced equation: 2 Na + 2 H2O --> 2 NaOH + H2

2)   2Co2O3 + 3C --> 4Co + 3CO2

3)

The balanced equation is:C12H22O11(aq)+H2O(I)-----> 4C2H5OH(aq)+4CO2(g)

4) 2Al(s) + 6HCl(aq) ? 3H2(g) + 2AlCl3(aq)
