CP

Question 1

speed of light

Answer 1

speed of light (c = 3 × 108 m/s)

Question 2

mechanical energy

Answer 2

Mechanical energy is made up of kinetic and potential energy, as it is associated with the motion and position of an object.

Question 3

Human hearing threshold frequency

Answer 3

20 Hz to 20 kHz

Question 4

What is conjugation?

Answer 4

When there are 3+ pi bonds together

Question 5

What is aromaticity? What is anti aromaticity

Answer 5

MAJOR KEY: need to count lone pairs in with pi electrons
When there are 4n+2 pi electrons- this increases stability
Anti aromaticity is when there are 4n- this is very unstable

Question 6

What do alkyl groups in a compound do to acid and base strength

Answer 6

Increase base strength, decrease acid strength. Why? Add electron density that makes a compound more able to accept H and less willing to donate H

Question 7

Formula for alkane, alkene, alkyne

Answer 7

alkane: CnH2n+2
alkene: CnH2n
alkyne: CnH2n-2

Question 8

Capacitors vs resistors in parallel

Answer 8

capacitors: increase in parallel, decrease in series
Mnemonic: PCs are good
resistors: decrease in parallel, increase in series
Mnemonic: RP (role playing) is bad

Question 9

what is a pyrrole?

Answer 9

A Nitrogen based ring
