Lisa [10]

Nuclear fusion in the sun involves hydrogen (H) atoms combining to form helium (He). A student claims that since the atmosphere contains hydrogen, any fusion reaction on Earth would result in an uncontrolled chain reaction. What is wrong in the student’s reasoning is that the uncontrolled chain reactions can only happen during nuclear fission.

Write sulfur dioxide reactions

scZoUnD [109]

Answer:

Sulfur dioxide is a covalent bond because we have two non-metals (Sulfur and Oxygen).

$S + O_{2} \to SO_{2}$ (Sulfur dioxide formula)

It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.

Sulfur dioxide can have different reactions:

In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:

$SO_{2}+\frac{1}{2} O_{2}= SO3$

The equal is because it's a reversible equation. This reaction is spontaneous.

The sulfur trioxide reacting with water produces sulfuric acid. The formula is:

$3 SO_{2} + O_{3} \to 3 SO_{3}\\SO_{3} + H_{2}O \to H_{2}SO_{4}$

Also the sulfur dioxide reacting with sodium hydroxide produces sodium sulfite and the formula is:

$SO_{2} + 2 NaOH \to Na_{2}SO_{3} + H_{2}O$

And finally we have the reduction of sulfur dioxide (it can be in presence of hydrogen sulfide) getting elemental sulfur and water. The formula is:

$SO_{2} + 2 H_{2}S \to 3 S + 2 H_{2}O$
