The atmosphere is thick and gaseous. The most common gases are helium and hydrogen.
Answer:
It will be C.
Explanation: If you read all of the other choices closely they don't make sense in context. (Option A) wouldn't make sense because removing things that could be reused would be inefficient to the body (and waste can't typically be reused in the human body). (Option B) growing too tall isn't particularly healthy or helpful, but it's not exactly life threatening either. And the very last choice is just nonsense period.
-1.09'C is the change in freezing point
“Freezing point depression” depends on the solvent and the molar concentration of the solute.
Sulfide is highly basic, consequently
K2S
completely and irreversibly hydrolyzes in water according to the following equation:
K2S+H2O→KOH+KSH
<h3>What is freezing?</h3>
Freezing, also known as solidification, is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.
the temperature at which a liquid solidifies specifically : the temperature at which the liquid and solid states of the substance are in equilibrium at atmospheric pressure : melting point the freezing point of water is 0° Celsius or 32° Fahrenheit.

The answer is yes. It's even safer compared to doing it from outside the vehicle.
The percent of O in Cr₂O₃ : 31.58%
<h3>Further explanation</h3>
Given
Cr = 52.00 amu, O = 16.00 amu
Required
The percent of O
Solution
MW Cr₂O₃ = 2 x Ar Cr + 3 x Ar O
MW Cr₂O₃ = 2.52+3.16
MW Cr₂O₃ =152 amu
