Acids. Sunlight and wind DO cause weathering, but not chemical weathering, just erosion. Only acids fundamentally alter the chemical structure of what it interacts or corrodes with.

What is the pressure in a 24.0-LL cylinder filled with 32.7 gg of oxygen gas at a temperature of 319 KK? Express your answer to
Blizzard [7]

Answer:

The pressure in that cylinder = 1.12atm

Explanation:

We use general gas law to calculate it. General gas law is gotten by combining Boyle's law, Charles' law and Avogadro's law. Thus

P = nRT/V

Where n = number of moles

R = the gas constant

T is the Temperature, V is the volume and P is the pressure.

Given: T = 319K, V = 24L, R = 0.0821 L.atm/K.mol

The first step is to find n using

n = mass of O2/molar mass of O2

=32.7/32

=1.0219

Now, using P =nRT/V

P = 1.0219 ×0.0821×319÷24

Therefore P = 1.12atm

The average speeds of gas molecules in cylinders A, B, C, and D are 0.01 m/s, 0.005 m/s, 0.1 m/s, and 0.5 m/s, respectively. Whi
Alik [6]
<span>We can relate the average speed of the gas molecules by its kinetic energy. The kinetic energy is the work done by the object due to its motion. It is represented by the formula of the half the velocity squared multiply by the mass of the object. The absolute zero theory is the assumption that at 0 Kelvin or -273.15 degrees Celsius, the gas molecules stop moving. It is because the temperature is severely cold enough to allow movement of the gas molecules. The gas molecule that is closest to the absolute zero is in cylinder B because it moves so slow and its movement is almost near to the absolute zero theory.</span>
