Answer: Option (B)

Explanation: The R-layer represents the unweathered rocks that are located below the surface and is the lowest layer in the soil profile. Here, hard rocks are found which are difficult to break, and are breakable with heavy machineries only. This R-layer makes the foundation of the soil profile that supports the entire overlying series of layers.

Thus, the correct answer is option (B).

What is the volume, in liters, of 1.40 mol of oxygen gas at 20.0°C and 0.974 atm?

topjm [15]

Answer:

V = 34.55 L

Explanation:

Given that,

No of moles, n = 1.4

Temperature, T = 20°C = 20 + 273 = 293 K

Pressure, P = 0.974 atm

We need to find the volume of the gas. It can be calculated using Ideal gas equation which is :

PV=nRT

R is gas constant, $R=0.08206\ L-atm/mol-K$

Finding for V,

$V=\dfrac{nRT}{P}\\\\V=\dfrac{1.4\times 0.08206\times 293}{0.974 }\\\\V=34.55\ L$

So, the volume of the gas is 34.55 L.
