02. Using Tables 1 to 3, what pattern do you observe in terms of the phase and number of carbon atoms of the alkanes, alkenes, a
BabaBlast [244]

Hey there mate ;), Im Benjemin and lets solve your question.

★ (Alkanes) : forms single bonds between carbon atoms.

The first four elements are gases and others are liquid in state.

★(Alkenes) : forms double bonds between carbon atoms.

The first three alkenes are gases and rest are liquid.

★ (Alkynes) : forms triple bonds between carbon atoms.

First three are gases and the last one is liquid.

According to boiling point :

The larger structure of the hydrocarbons, the higher the boiling points they have.

In the 3 tables, we can see that the boiling point increases.

The reaction of aluminum with chlorine gas is shown.
mr Goodwill [35]

Answer:

See below

Explanation:

The equation shows    Al / Cl  = 2/3      or    3/2 Al = Cl

                                                                        3/2(20) = 30 Cl atoms needed

The equation shows a one-to-one relationship between Al and AlCl3

   produced     so if you use 20 Al atoms you get 20 AlCl3 molecules
