Answer:
MECHANISM:
1) The lone pair on oxygen attacks the H-Br molecule forming a hydronium ion.
2) Formation of carbocation.
3) Attack of Nucleophile Br − .
Explanation:
Answer:
A.) False B.)False C.) True D.) False E.) False
Explanation:
Actually Rb or Rubidium in zero state has the following
electron configuration:
<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>
However we can see that the ion has a 1 positive charge,
which means that it lacks 1 electron, therefore the answer from the choices is:
<span>d.
rb+: 1s22s22p63s23p64s23d104p6</span>
Answer:
Research that releases a poisonous gas into the air.
Explanation:
Since I don't know the options I will guess it is ^
A substance through which an electrical current flows poorly would be said to be a poor conductor. That is, the substance has a low conductance (or conductivity). There’s a nuance between the two terms, but it shouldn’t matter for our purposes.
Since such a material resists the flow of electric charge, the material can be said to have a high resistance (or high resistivity).
Mathematically, resistance and conductance are reciprocals of one another; a low conductance implies a high resistance, and a high conductance implies a low resistance.
