A molecular formula represents the exact number of atoms present for each element in the compound.
For carbon atom: 
= 
( as molar mass of carbon is 12 g/mol)
Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6
Thus, formula becomes 
( 
Now, check for unsaturation:
Degree of unsaturation = 
Substitute the value of x and y,
Degree of unsaturation = 
= 
= 
implies one ring and three double bonds.
Thus, formula comes out to be i.e. benzene ring.
Explanation:
The nitrogen dioxide is a covalent compound where one nitrogen is the central atom which is bonded to two oxygen atoms, where one oxygen atom is bonded by a single bond and other oxygen atom by a double bond.
Answer:
Alkanes
Explanation:
The description of the first molecule corresponds to a cycloalkane. In the cycloalkanes for each carbon atom there are 2 hydrogen atoms (CnH2n = C5H10).
The second molecule corresponds to an open chain alkane, where for every carbon atom there is double plus 2 hydrogen atoms (CnH (2n + 2) = C5H12)
It is being aware of things around you and the decisions you make. Being in control of your own actions.
False the output force and input force is low because the formula is output force divided by input force. Just a note you are not doing much input force into the screw because you hold the screwdriver
