To answer the first question we can say that that line is associated with a transtition between an excited state and the ground state. We can explain this <span>transitions in the Lyman series, which appear in the UV region of the spectrum and all terminate at the ground electronic state of the hydrogen atom. Now for the second question I have always known that the value of n1 of this transition is 1. And the wavelenght of the longest wavelenght photon that a ground state hydrogen can absorb is 121.5 nm</span>
Answer:
None of the species in the equation have undergone either oxidation or reduction
Explanation:
The easiest way to see if oxidation or reduction has happened is to compare oxidation numbers of each and every species before and after the reaction.
Calcium is two before the reaction and two after the reaction
Hydrogen is -1 before the reaction and -1 after the reaction
Sodium is one before the reaction and one after the reaction
Iodine is -1 before the reaction and -1 after the reaction.
For an oxidation to happen an increase in oxidation number has to happen.
For a reduction to happen, a decrease in oxidation number has to happen. None have happened
Answer: T2= 962.2 K
Explanation:
The ideal gases is often written like PV=nRT, where P is pressure, V is volume, n is moles, R is the universal constant of the gases and T is Temperature.
So, in this problem there is a container that is a closed system, therefore n is constant and volume too. The initial point is 1 and the final point is 2, so
V1=V2 ⇒
Well. Yeah. Basically.
1 mole of any gas is 22.4 L.
Not really sure if that answers your question but that's what i know.
Anyway if we are talking about the size then usually gases are filled with empty space.
The reason for this is that <span>these two ketones are so small that they have only one possible ketone. So the number is usually omitted. Normally the ketone group needs a number but these two are exceptions</span>
