The amount of parent and daughter material trapped in the rock.
<span>Mnemonics for Functional Groups
These are possible mnemonics for the common functional groups.
Vowels: The vowels "A", "E", and "Y" for Alkane, Alkene, and Alkyne.
Remember there is no "I." "O" and "U" would result in awkward pronunciations.
Alcohol: Look for the "C-O-H" in "Alcohol."
Ether: Ethers were anesthetics used in the 1800s.
Dr. Kellogg also lived at the same time. Corn Flakes are made by Kellogg's. A rooster or wingspan (C-O-C) is the cornflake mascot.
Amine: Remember the "N" stands for nitrogen.
Aldehyde: This sounds like "Adelaide," the Australian city.
Australia is at the end of the Asian islands, and aldehydes are at the end of the hydrocarbon chain. The "Y" indicates a C=O double bond.
Ketone: Imagine the diagonal strokes of "K" forming the C=O double bond.
Carboxylic Acid: "Box" stands for boxed wine or C-O-H, alcohol. The "Y" indicates a C=O double bond.
Ester: This sounds like "Estelle" George Costanza's mother in the TV show Seinfeld. George's nickname was Koko or Coco. So think of O=C-O-C.
Amide: Amine with a "D". D for double.</span>
The mass in kg of the water on the roof after the rainstorm is mathematically given as
The mass of the water on the roof after a rainstorm is 1.1 *10^{10}g or 1.1*10^{7}kg
<h3>What is the mass in kg of the water on the roof after the rainstorm? </h3>
Generally, the equation for the Area of the roof is mathematically given as
height of the rain =5.5cm
the volume of the rain on the roof =1.1 * 10^{10} CC
Generally, the equation for mass is mathematically given as
mass=volume*density
In conclusion, the Mass of the water on the roof after a rainstorm is 1.1 *10^{10} or $1.1*10^{7}

Explanation:
Given the data:
__X____Y
$20 __$17.50
$21 __ $18.50
$22__ $19.50
$23__ $20.50
Using a linear regression calculator :
The linear regression model obtained is :
y = -2.5 + x
Where ; - 2.5 = intercept ; gradient / slope = 1
