Answer: false
Explanation:
When two atoms come sufficiently close together the valence electrons of each atom experience the attractive force of the nucleus in the other atom. The nucleus and the electrons in the inner shell remain unaffected when atoms come close together.
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:
Difference in temperature.
Explanation:
Conduction is the movement of heat energy through a substance or from one substance to another by direct contact of atoms and molecules. Heat moves directly from one molecule to another. The heat energy speeds up the movement of the atoms and they collide with other molecules setting them into faster motion.
I think if was chemical energy hope I helped
Answer: I believe this statement is true.
Explanation: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Sorry if this is wrong, it is just what i believe.
