How many electrons are being shared between the atoms in this molecule

1 answer:

5 0

. The formula for methane is CH4. There are 8 total valence electrons - 1 each for the hydrogen atoms, and 4 for the carbon atom. There are four single bonds, and no lone electron pairs in the methane molecule. With 8 valence electrons and 4 single bonds, we get 8/4=2 electrons per bond.

2. The methane molecule contains four single, or sigma, bonds. Each sigma bond is formed between the 1s orbital of a hydrogen atom, which contains one electron, and one of the four hybrid sp3 orbitals of the carbon atom, each of which contains one electron. That gives us 2 electrons per bond.

Eva is in a closed, dark room. She uses her arm muscles to turn on a lamp. When she moves her hand closer to the lamp, the light

Well, we know that the total energy in a closed system remains constant.

The problem with the story of Eva is that she is not in a closed system.
If the dark room were really a closed system, then she could press the
button or turn the switch all day, and the lamp could not light. It needs
electrical energy coming in from somewhere in order to turn on.

Let's say that Eva used her arm muscles to strike a match and light the
candle on the table. Then we would have have food energy, muscle
energy, chemical energy in the match, chemical energy in the candle,
heat and light energy coming out of the candle, heat energy soaking into
her hand, light energy bouncing off of the book and into her eyes ... all
going on during the story, and the sum total of all of them would remain
constant.
