Step 1

The complete oxidation of glucose (C₆H₁₂O₆) in plant and animal cells.

Answer

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

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

This reaction indicates that one molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide and six molecules of water.

Step 2

The formation of helium by nuclear reaction in the sun.

Answer

The formation of helium through nuclear fusion in the sun is represented by:

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

This reaction illustrates the fusion of hydrogen nuclei (protons) to form helium, along with the production of positrons and neutrinos.

Step 3

Answer

The reaction between ammonia (NH₃) and sulfuric acid (H₂SO₄) to produce ammonium sulfate ((NH₄)₂SO₄) can be expressed as:

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

Step 4

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

Answer

The reaction of sulfur trioxide (SO₃) with aqueous sodium hydroxide (NaOH) results in the formation of sodium sulfate (Na₂SO₄). The balanced equation is:

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