Answer:
True
Explanation:
Atmospheric pressure reduces the amount of oxygen in the air, therefore leading to Hypoxia. Higher altitues contribute.
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 10L of H₂S should react with 6.6L of oxygen at stanadard pressure and temperature.

What is ideal gas equation?</h3>
Ideal gas equation is the mathematical expression that relates pressure volume and temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
P×V=n×R×T
where,
P = pressure of gas
V= volume of gas
n =number of moles of gas
T =temperature of gas
R = Gas constant = 0.0821 L.atm/K.mol
At Standard temperature and pressure, 2 moles of H₂S react with 3 moles of 0₂. S0, 10L of H₂S should react with 0.66×10=6.6L of oxygen.
Therefore, 10L of H₂S should react with 6.6L of oxygen.

Answer:
we will take a 100g sample of this solution for our convenience
so , there is 15 g kBr in this 100g solution
we know that molality is the number if moles of solute / mass of solvent in kg
we need to find the number of moles in 15g kBr
no of moles = 15/119 s
moles = 0.126 moles/ 100g
multiplying both the numerator and the denominator by 10 to get 1 kg in denominator
= 1.26 moles / 1 kg
Hence, the molality is 1.26

Answer:
Explanation:
We know that the speed of light is equal to 
We need to find how far the light travel in 3 days.
Speed of an object is equal to distance covered divided by time taken.
Also, 1 day = 86400 s
3 days = 259200 s
So,
So, the light will travel 
in 3 days.
