Answer:
The molecules absorb heat and acquire more kinetic energy.
Explanation:
In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.
When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.
The temperature remains constant until phase transition is over, then temperature rise resumes.
Answer:

Number of Electrons 38
Answer:
Explanation:
Gilman reagent is also known as the Lithium organocuprates. They are used as nucleophiles in the organic synthesis.
Gilman reagent is used for C - C bond formation.
H H H

-----→ H - C -- C -- C -- C =
(1 bromo propane) | | | |
H H H H
(1 pentene)
Normally in C--C formation by Gilman reagent, the following reactions takes place :
R -- Br + R--R' + R' Cu + Li Br
In 1 pentene, i.e.
(from 1 bromo (from Gilman reagent)
propane)
So Gilman reagent is
Organo lithium compound is
Answer:
it would be the second option. It responds to stimuli to help protect an organism and maintain structure
