Burning a candle is a combustion reaction that uses wax and oxygen to produce carbon dioxide, water, and energy. when you burn a candle down in an open room, the limiting reactant is

The wax

Explanation:

The limiting reactant is the reactant in short supply in a particular reaction. This reactant determines the extent of the reaction. Oxygen in the reaction is the one in excess. As we know that oxygen is free in the atmosphere and it is in excess supply.

After the wax finishes burning the reaction stops and no more production of carbon dioxide, water and energy but oxygen still continues to abound all around.

In order to determine the amount of carbon dioxide and water that would be produce, we simply use the amount of wax to relate with them.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
