At standard temperature and pressure, the volume of 58 gms of chlorine gas is 7.08 L.
<h3>What is STP?</h3>
STP is the condition of the ideal gas that relates to the moles, pressure, temperature, and volume. The ideal gas law at the STP is given as:
PV = nRT
Given at STP,
Pressure (P) = 1 atm
Temperature (T) = 273 K
Gas constant (R) = 0.0821 L atm/ mol K
Moles (n) of chlorine gas is calculated as:
Moles = Mass / Molar mass
n = 58.0 / 70.90
= 0.818 moles
The volume for the ideal gas equation is calculated as:
V = n * R * T / P
V = 7.08 / 1
V = 7.08 L
Therefore, at STP the volume of the gas is 7.08 L.

Answer:
A primary source of energy is a fossil fuel , nuclear fuel , wind or sunlight in an unconverted state . A secondary source of energy is created when a primary source of energy is burned or otherwise converted into a form , like electricity, that can be used for useful work.
Explanation:
Answer: normal fault
A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.
On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.
Answer:
λ=2167.6 nm
The wavelength of light emitted is 2167.6 nm.
Explanation:
We recall that Eₙ=
since there was transition from n7 to n=4 we will first calculate the change in the energy i.e ΔE
ΔE=E₄-E₇
ΔE=
ΔE=-9.1760*10^-20 J
Now:
|ΔE|=Energy of photon=h*v=h*c/λ
λ=h*c/|ΔE|
λ=
λ=2.1676*10^-6 m
λ=2167.6*10^-9 m
λ=2167.6 nm
The wavelength of light emitted is 2167.6 nm.
