are produces are in a month.
What happens when carbon dioxide builds up in your lungs?
If the person's breathing passage were filled with carbon dioxide instead of air, it would lead to respiratory failure.
Signs of respiratory failure:
- The symptoms of respiratory failure depend on the cause and the levels of oxygen and carbon dioxide in your blood.
- The inability to breathe in enough air and shortness of breath are both signs of low blood oxygen levels. Your fingernails, skin, and lips could all be blue in hue.
- Rapid breathing and confusion can occur when there is a high carbon dioxide level.
- Those who experience respiratory failure can lose consciousness or become extremely tired. Arrhythmia (irregular heartbeat) may also exist in them. If your brain and heart aren't getting enough oxygen, you can experience these symptoms.

Answer:
0.570 L
Explanation:
Given:
Concentration of the HCl solution = 0.750 M
Mass of NaCl in the reaction = 25.0
Number of moles of NaCl in the reaction = Mass of NaCl / Molar mass of NaCl
also,
Molar mass of NaCl = 22.98 + 35.45 = 58.43 grams
thus,
Number of moles of NaCl in the reaction = 25 / 58.43 = 0.4278 moles
now,
1 mol of NaCl reacts to form 1 mol of HCl
thus,
0.4278 moles of NaCl reacts to form 0.4278 mol of HCl
also,
Concentration = Moles / volume of solution
0.750 = 0.4278 / volume of solution
or
volume of solution = 0.570 L
Answer:
A piece of paper
Explanation:
The emitted radiations are helium nuclei which is also called alpha particle. The alpha radiations can be stopped by a piece of paper. While beta radiations can be blocked by the sheet of aluminium and Lead is used for the protection against gamma radiations because of its high molecular density.
Alpha radiations:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
