Equals C equals is not a correct bond. In order to create a bond, you will need to have an elemental symbon on either side of the equal sign. C equals C would be a correct bond type.

correct anser is C ; y=-45
If the following are the definitions of the symbols referenced in the question: c = circumference r = radius d = diameter l = length w = width then NONE of the formulas listed in the question is correct. The circumference of a circle is (pi) times d. d is the diameter, (pi) = 3.14156 (rounded)
by transitive property
That is the correct formula for converting degrees Celsius (or Centigrade) to degrees Fahrenheit.
C=C represents a carbon double bond. It basically shows that there are two bonds between the caron atoms so it is very strong.
H2C=C=CH2, 6 sigma and 2 pi bonds.
You can form a C-C which is a single bond carbon and you can form a C equals C which is a double bond carbon. But if you were to form a triple C bond then the remaining 2 electrons that are located on the other side of the triple bond cannot form a bonding pair.

The correct answer is co2+c= 2co
The correct Lewis structure for a molecule of the compound C2H2 contains an alkyne bond. This is a triple bond between two C atoms. It has a linear bond geometry and no lone pairs.
a = 2b + c then a - 2b = c ie c = a - 2b
Single bond.
sp2 hybrid orbitals overlap.
No. In terms of bond strength a C-C bond is stronger than a C-N bond.
It is a covalent bond.
Yes. In CH3Cl, there is one C-Cl bond and three C-H bond.
