Explanation:
He used just the right amount of matter in water to get it to evaporate at a normal temperature and to condense into clouds for rain.
Answer:
electron revolving in a shell is associated with a definite amount of energy. The energy changes when it jumps to another shell that is so say when it goes from one level of energy level to another. Thus shell also gives the energy of a electron besides its location and are therefore called energy levels.
Answer:
The product is 1-methylcyclopentanol
Explanation:
The acid-catalyzed hydration of alkenes involves the addition of a water molecule to a C=C double bond.
H₂O + C=C ⟶ H-C-C-OH
An H atom adds to one of the C atoms, and an OH group adds to the other
This reaction follows Markovnikov’s rule — the H adds to the C atom that has more hydrogen atoms, and the OH adds to the more substituted carbon.
The steps of the mechanism are:
- The aqueous sulfuric acid generates hydronium ions
- The nucleophilic π electrons attack an H atom on the hydronium ion, forming a carbocation on the more substituted C atom.
- The lone pair electrons on a water molecule attack the carbocation , forming an oxonium ion.
- Another water molecule removes the extra proton.
The product is the alcohol with the OH group on the more substituted carbon — 1-methylcyclopentanol.
ANSWER:
Most of them are silver, they all have a face on them.
