Answer: The carbon atom in Chloroform has
FOUR bonding pair electrons and
ZERO lone pair of electrons.
Explanation: The carbon atom in Chloroform is bonded to three chlorine atoms and one hydrogen atoms through a single bonds. And the carbon is sp³ hybridized. As we know the electronic configuration of carbons is,
Ground State = 1s², 2s², 2p²
Excited State = 1s², 2s¹, 2px¹,2py¹, 2pz¹
As there are four unpaired electrons in excited state which are all involved in bonding with chlorine atoms and hydrogen atom, therefore, no lone pair of electrons are left.
If they are constantly being formed then, they are called renewable energy. So the statement above is false. B.
Answer:
Which statement is true about the particles of a solid when the solid changes into a liquid? (5 points)
a. They stop vibrating.
Selected: b. Their kinetic energy increases. This answer is correct.
c. They move closer to each other.
d. The attractive force between them increases.
Explanation: when a solid turns to a liquid it means it was melted and it needs to be heated to melt meaning the kinetic energy increases because the solid was heated up. Also this was on my test and i got it right so yeah.
Chemistry is a major part of science that discusses the elements and basic substances of forms of life. It helps investigate how things grow and change and how they react over time.
Complete the mechanism for the reaction of 2-methylbutan-2-ol in sulfuric acid at 140 °C by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows. Note the use of a generic alcohol to represent another 2-methylbutan-2-ol introduced in panel three.
