You can't tell the relative values of I-1 and I-2 from the information given,
but that's not for any super-technical reason.
The reason is because the drawing doesn't show WHERE in the circuit
I-1 and I-2 are measured.
It makes a BIG difference if they're the currents in the resistors, or
the currents in and out of the battery.
-- The currents in and out of the battery are equal.
-- The current through either resistor is less than
the current in or out of the battery.
-- The sum of the currents through both resistors
is equal to the current in or out of the battery.
-- The currents through the two resistors may be equal
or unequal, and either one may be greater or less than
the other. It all depends on the values of the resistors.
Answer:
the H from the HCl switched places with the Fe from the FeS.
Answer:
First Question

Second Question
The wavelength is for an X-ray
Explanation:
From the question we are told that
The width of the wall is 
The first excited state is
The ground state is 
Gnerally the energy (in MeV) of the photon emitted when the proton undergoes a transition is mathematically represented as
![E = \frac{h^2 }{ 8 * m * l^2 [ n_1^2 - n_0 ^2 ] }](https://tex.z-dn.net/?f=E%20%20%20%3D%20%20%20%5Cfrac%7Bh%5E2%20%7D%7B%208%20%2A%20m%20%20%2A%20%20l%5E2%20%5B%20n_1%5E2%20-%20n_0%20%5E2%20%5D%20%7D)
Here h is the Planck's constant with value 
m is the mass of proton with value 
So
![E = \frac{( 6.626*10^{-34})^2 }{ 8 * (1.67 *10^{-27}) * (10 *10^{-15})^2 [ 2^2 - 1 ^2 ] }](https://tex.z-dn.net/?f=E%20%20%3D%20%20%20%5Cfrac%7B%28%206.626%2A10%5E%7B-34%7D%29%5E2%20%7D%7B%208%20%2A%20%281.67%20%2A10%5E%7B-27%7D%29%20%20%2A%20%20%2810%20%2A10%5E%7B-15%7D%29%5E2%20%5B%202%5E2%20-%201%20%5E2%20%5D%20%7D)
=> 
Generally the energy of the photon emitted is also mathematically represented as

=> 
=> 
=> 
Generally the range of wavelength of X-ray is 
So this wavelength is for an X-ray.
When atmospheric pressure is higher than the absolute pressure of a gas in a container.
