Answer:
I think it's B
Explanation:
I think it is b because if the number is positive the zeroes will be on the left so you move the decimal to the right to get rid of the zeroes.
The general form of a compound can be written in the form
of:
[X(a) Y(b)] ^ c
Where a and b are subscripts, and c is the superscript of
the whole formula.
The relationship that we can derived here between the
constants is:
(valence of X) * a + (valence of Y) * b = c
Since the formula obviously has no superscript, therefore
c = 0. We also know in chemistry class that the valence of Cl is -1, therefore:
valence of X * 1 + (-1) * 3 = 0
valence of X - 3 = 0
<span>valence of X = 3</span>
Answer:
Due to an electron-pair acceptor and donor.
Explanations:
<em><u>Lewis acid</u></em> can be defined as an electron-pair acceptor. An example is Hydrogen ion(H+). This is because it is a proton and it distributes positive charge which means that it accepts electrons(negative charge).
<em><u>Lewis base</u></em> can be defined as an electron-pair donor. This is because it donates electrons to be accepted by the proton. An example is ammonia(NH3).
Answer:
Look on the picture.
Explanation:
He could find only 2 isomers of n-hexane alkenes for this reaction. Other two could be marked from other direction.
