Answer:
C
Explanation:
Calculate the number of moles of Al2O3 that are produced when 15 mol of Fe is produced
in the following reaction.
C) 45 mol
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:
Prop-1-yn-1-ide
Explanation:
In this case, we will have an <u>acidic hydrogen</u> upon the left carbon in the alkyne. In the presence of a<u> base</u>, we can <u>remove</u> this hydrogen. In this reaction the base will be 
. The <u>amidure ion</u> will remove the hydrogen of the alkyne to produce a <u>carboanion</u>. (See figure)
Pentane consist of 5 carbon atom and have the shape of a pentagon...
one C atom is bonded to 2 other C atom and in addition 2 other H atom
so one C atom will be bonded to 4 other atom in total and hence sharing all its available electons
