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.

Palm to palm is referred to as the best way to maintain control of the subsection when cutting with a vertical or diagonal cutting line thereby preventing the risk of injuries or inaccuracy.
<h3>What is Palm to palm technique?</h3>
This method is used during cutting or styling and involves the two palms of the hands in a position such that they are facing each other or opposite to one another and helps to reduce the different types of strain in the affected part of the body.
This method isn't a compulsory one to be done but is best suited for an individual who wants to maintain control of the subsection when cutting with a vertical or diagonal cutting line.
This is therefore the main reason why palm-to palm technique was chosen as the most appropriate choice.

Answer:
D- lower central air pressure
Answer:
Explanation:
1)<u><em> Ionization equilibrium equation: given</em></u>
- H₂O(l) + H₂O(l) ⇌ H₃O⁺(aq) + OH⁻(aq)
2) <em><u>Ionization equilibrium constant, at 25°C, Kw: given</u></em>
<u>3) Stoichiometric mole ratio:</u>
As from the ionization equilibrium equation, as from the fact it is stated, the concentration of both ions, at 25°C, are equal:
- [H₃O⁺(aq)] = [OH⁻(aq)] = 1.0 × 10⁻⁷ M
- ⇒ Kw = [H3O⁺] [OH⁻] = 1.0 × 10⁻⁷ × 1.0 × 10⁻⁷ = 1.0 × 10⁻¹⁴ M
<u><em>4) A solution has a [OH⁻] = 3.4 × 10⁻⁵ M at 25 °C </em></u><em><u>and you need to calculate what the [H₃O⁺(aq)] is.</u></em>
Since the temperature is 25°, yet the value of Kw is the same, andy you can use these conditions:
Then you can substitute the known values and solve for the unknown:
- 1.0 × 10⁻¹⁴ M² = [H₃O⁺] × 3.4 × 10⁻⁵ M
- ⇒ [H₃O⁺] = 1.0 × 10⁻¹⁴ M² / ( 3.4 × 10⁻⁵ M ) = 2.9⁻¹⁰ M
As you see, the increase in the molar concentration of the ion [OH⁻] has caused the decrease in the molar concentration of the ion [H₃O⁺], to keep the equilibrium law valid.
