Answer:

Explanation:
The Rydberg equation gives the wavelength λ for the transitions:

where
R= the Rydberg constant (1.0974 ×10⁷ m⁻¹) and

Data:

λ = 657 nm
Calculation:

Answer:
Hexane.
Explanation:
Hello!
In this case, since the general reaction of the compound C4H14 with chlorine is:

Which stands for a substitution chemical reaction in which one chlorine is able to replace one hydrogen and therefore hydrogen chloride gives off; we infer that the initial compound, C4H14, shows off the
formula characteristic of alkanes; in such a way, as it has six carbon atoms, we infer it is hexane.
Best regards!

Answer:
It would appear that the H2 gas is collected in a stoppered flask. Therefore, the volume of the gas is 138 mL minus the 5 mL occupied by the HCl, or 133 mL.
Explanation:
<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.
<u>Explanation:</u>
Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.
In beta-minus decay, a neutron gets converted to a proton and an electron.
The equation for the beta-minus decay of carbon-14 follows the reaction:

In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.
In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.
