Answer

The complete oxidation of glucose can be represented by the balanced chemical equation:

$C_6H_{12}O_6(aq) + 6 O_2(g) \rightarrow 6 CO_2(g) + 6 H_2O(l)$

In this equation, glucose reacts with oxygen to produce carbon dioxide and water.

Step 2

b. The formation of helium by nuclear reaction in the sun.

Answer

The formation of helium through nuclear fusion in the sun can be simplified by the following reaction:

$4 H \rightarrow He + 2 e^+ + energy$

Here, four hydrogen nuclei (protons) fuse to form one helium nucleus, along with the production of positrons and energy.

Step 3

c. The reaction between ammonia and sulfuric acid to form ammonium sulfate fertiliser.

Answer

The balanced equation for the reaction between ammonia and sulfuric acid to produce ammonium sulfate is:

$2 NH_3(g) + H_2SO_4(aq) \rightarrow (NH_4)_2SO_4(aq)$

In this reaction, two molecules of ammonia react with one molecule of sulfuric acid to form ammonium sulfate.

Step 4

d. The reaction of an oxide of sulfur with aqueous sodium hydroxide.

Answer

The reaction of sulfur trioxide (SO3) with aqueous sodium hydroxide (NaOH) can be represented as follows:

$SO_3(g) + 2 NaOH(aq) \rightarrow Na_2SO_4(aq) + H_2O(l)$

In this equation, one molecule of sulfur trioxide reacts with two molecules of sodium hydroxide to produce sodium sulfate and water.
