Justify why you can or cannot make a compound out of 6 hydrogen atoms and 2.5 carbon atoms.

Stoichiometric compounds are composed of whole number ratios of constituent atoms.

Explanation:

In accordance with Dalton's law, when atoms combine to form compounds, they do so in simple whole number ratios.

Hydrocarbons compounds are compounds of hydrogen and carbon. The hydrogen and carbon usually combine in simple whole number ratios. The ratio of hydrogen atoms to carbon atoms in organic compounds is never fractional.

Combination of 6 hydrogen atoms and 2.5 carbon atoms do not represent simple whole number ratio of combination of constituent atoms hence it is not possible to make such a compound. There can never be a hydrocarbon containing the said ratio of hydrogen to carbon atoms.

neutrons are in the middle of the atom and the electrons, which are much smaller.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
