Visual representation of covalent bonding indicating the valence shell electrons in the molecule, lines represents the shared pair of electron and pair of electrons that are not involved in bonding are represented as dots(lone pairs) are known as Lewis structures.
Compound formation takes place in order to complete the octet of each element that is according to octet rule, each atom forms bond with other atom in order to complete their octet that is to get eight electrons in its valence shell and attain stability.
An organic compound of the form is known as ketene.
The given ketene is .
The number of valence electron of:
The number of valence electrons in =
2 electrons are involved in each single bond between carbon and hydrogen and 4 electrons are involved in each double bond formed between carbon-carbon and carbon-oxygen. Hence, the total number of electrons involved in bond formation are 12 and rest 2 pair of electrons are present on oxygen as lone pair of electrons.
Therefore, the attached image is the Lewis structure of .
<u>Answer:</u> The mass of ice is
<u>Explanation:</u>
We are given:
Area of Antarctica = (Conversion factor:
)
Height of Antarctica with ice = 7500 ft.
Height of Antarctica without ice = 1500 ft.
Height of ice = 7500 - 1500 = 6000 ft = (Conversion factor: 1 ft = 30.48 cm)
To calculate mass of ice, we use the equation:
We are given:
Density of ice =
Volume of ice = Area × Height of ice =
Putting values in above equation, we get:
Hence, the mass of ice is
