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.

Textiles for clothes are also sometimes finished with chemicals, for example, to stiffen them and make them wrinkle-free. Chemicals in their nanoforms are helping make textiles more resistant to water, stains, wrinkles, bacteria and mould. Some of the chemicals can be harmful.

Answer:
3.97× 10²³ atoms of Ag
Explanation:
Given data:
Mass of Ni = 112 g
Mass of AgNO₃ = 112 g
Atoms of silver produced = ?
Solution:
Chemical equation:
Ni + 2AgNO₃ → 2Ag + Ni(NO₃)₂
Number of moles of Ni:
Number of moles = mass/ molar mass
Number of moles = 112 g/58.7 g/mol
Number of moles = 2 mol
Number of moles of AgNO₃:
Number of moles = mass/ molar mass
Number of moles = 112 g/169.87 g/mol
Number of moles = 0.66 mol
Now we will compare the moles of Ag with both reactants.
AgNO₃ : Ag
2 : 2
0.66 : 0.66
Ni : Ag
1 : 2
2 ; 2×2= 4 mol
Number of moles of Ag produce by AgNO₃ are less so it will limiting reactant and limit the yield of Ag.
I mole = 6.022 × 10²³ atoms
0.66 mol × 6.022 × 10²³ atoms / 1 mol
3.97× 10²³ atoms of Ag
