Which line-angle formula represents an alkene?
Vladimir79 [104]

Answer:

Option 3.

Explanation:

Alkenes are generally unsaturated hydrocarbon with carbon to carbon double bond (C=C).

From the options given above, only option 2 and 3 contain carbon to carbon double bond (C=C).

Option 2 is called a benzene ring and not an alkene. Benzene are not classified as alkenes because the double bond between the carbon can not be broken i.e benzene does not undergo addition reaction like the alkenes. Benzene tends to show more stability than the alkenes.

This leaves us with option 3 as the answer to the question because it contains carbon to carbon double bond (C=C)

A ballon is filled with helium gas. Another balloon, of the same size, is filled with nitrogen gas. Explain why the ratio of the
LenaWriter [7]
Let's say say there are n1 mols of helium in the first balloon and n2 mols of nitrogen in the second one, which are equivalent to m1 grams of helium and m2 grams of nitrogen.

The molar mass of hydrogen is thus M1=m1/n1, same for nitrogen M2=m2/n2 hence the ratio of their masses is m1/m2=(M1n1)/(M2n2). Since both gases are rather similar, we can assume that n1~n2 hence m1/m2=M1/M2
