CASE-STUDY
CASE
Today, we find many spruces around our cities and especially around hospitals. A gas accumulates in the air of spruce forests. If patients with tuberculosis breathe in this gas, their recovery will be accelerated. 4.48 liters of this gas interacted with the silver earrings and the earrings turned into a black compound?

We use the “mental attack” method on Case. Cases are solved en masse.

Assignments:

1. Which gas is released?

2. Why did patients recover when they inhaled this gas?
3. What is a black compound? 4. How many black compounds were formed?

Case solution:

1) It was found that the spruce plant emits ozone (O₃) gas into the air.

2) Ozone gas is unstable and decomposes into molecular and atomic oxygen. When you breathe in air mixed with ozone, the disease heals quickly under the influence of atomic oxygen.
3) Ag₂O. 4) 24.8 g

Interesting questions:
Humans consume large amounts of drinking water throughout their lives. Dirty water is the plague of the century. Dirty water is cleaned from various mechanical and chemical compounds and from bacteria, viruses, microbes and pests that spread disease. Chlorine, sodium hypochlorite, hydrogen peroxide and ozone are used for this purpose. Which of these cleans the water almost 100%?

Answer: Ozone

Interesting questions:
This substance can kill all living things in large concentrations. It is the second strongest oxidizer after fluoride. Interestingly, when it is formed in the atmosphere in a thunderstorm charge, it becomes easier to breathe.
