Methane gas, which may be present in confined spaces such as a basement, can cause death by asphyxiation.
<h3>
What are the dangers of methane gas in confined space?</h3>
Low amounts are safe for inhalation. A significant amount can replace oxygen in the atmosphere. Reduced oxygen availability can cause symptoms like weariness, emotional instability, fast breathing, and rapid heart rate. Insufficient oxygen can cause nausea, vomiting, collapse, convulsions, coma. The onset of symptoms is accelerated by physical activity. Organs including the heart and brain can suffer long-term damage from a lack of oxygen.
Contact with Skin: Not irritating. The skin might become chilled or frozen when in direct touch with the liquid gas (frostbite). Itching and numbness are signs of mild frostbite. Burning and rigidity are signs of more serious frostbite.
No evidence of carcinogenicity.

60
Explanation:
The number of electrons in an atom of Q-95 will be 60 electrons.
The atomic number of an atom is the number of protons in the atom of the isotope
This number is unique to every atom and their isotope
An isotope of an atom is the existence of an atom having the same atomic number but different mass numbers.
Since atomic number the same as number of protons, they are the positively charged particles in an atom.
To have a negative charge, the number of electrons must be more than that of protons.
Charge = number of protons - number electrons
charge = -1
-1 = 59 - number of electrons
Number of electrons = 60 electrons

Answer:
Modern periodic law
Explanation:
There are many ways of stating the modern periodic law. Generally, the modern periodic law states that the properties of elements are a periodic function of their atomic numbers. That means, similar properties recur periodically when elements are arranged according to increasing atomic number.
Two scientists were largely responsible for our present day understanding of the modern periodic law, they are, Mendeleev and Moseley. Their work laid the foundation for the periodic table in its current form.
Answer:
P₂ = 13.79 atm
Explanation:
Given data:
Initial volume = 196.0 L
Initial pressure = 1.83 atm
Final volume = 26.0 L
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.83 atm × 196.0 L = P₂× 26.0 L
P₂ = 358.68 atm. L / 26.0 L
P₂ = 13.79 atm
