Answer:
See explanation
Explanation:
I know that we usually associate the sp3 hybridization to the tetrahedral shape. This is common in molecules such as CH4. So it may sound somewhat strange that NH3 molecule has an sp3 hybridized nitrogen atom and a trigonal pyramidal geometry.
Let us recall that the central nitrogen atom in NH3 has a lone pair of electrons. These lone pairs causes more repulsion than bond pairs. As a result of the presence of this lone pair, the bond angle in the NH3 molecule is distorted away from the expected 109.7 degrees in tetrahedral geometry and the bonding groups are now arranged in a trigonal pyramidal geometry(with bond angle less than 109.7 degrees) to minimize electron pair repulsions.
Answer:
Drain Cleaner, soap, bleach
i think thats it, sorry if i got something wrong
The atomic size decreases; this is because as you go across the period, more electrons are found in the outer shell. As more electrons are added, the more attraction there is between the protons, in the nucleus, and the electrons, making the atom smaller.
Hope this helps!

<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>
