How do chemical reactions become balanced?

the molecules in the reaction react in ratios. for eg in water it is Hyogen and water in the ration 1:2. these ratios tell you how many of the atoms are required for the reaction.


How can you tell the difference between a phase change and when a chemical reaction produces a gas?

A phase change should not, in general, require more than one compound. A chemical reaction, by definition, will involve at least two compounds. The only "exception" would be a decomposition reaction, but in that case two different compounds would be formed so it's not really an exception.

Is a candle burns chemical reaction?

Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.Yes, whenever a candle burns, it is a combustion reaction between the carbon compounds of the wick and wax of the candle and of oxygen in the air. These compounds burn to create carbon dioxide and water, and also a few smaller carbon compounds, which is evident as the smoke rising occasionally from the flame. The flame you see and the heat you feel rising off of the burning wick is the evidence of an exothermic chemical reaction.Yes, burning a candle is a chemical reaction.
