To be honest i really don't kno but i need it for my science h/w 2morrow I've lookied everywhere, this site needs to be more detailed

Not sure how but you could spilt the candle in half and the do the physical on one side and the chemical on the other side.
The particle diagram should show particles of hydrogen and oxygen in the candle while particles of carbon dioxide should come out of it
Burning is a chemical change because the nature of molecules is changed.
Burning a candle is a chemical change. It cannot be "unburnt"
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
The melting of the wax is a physical change. The burning the of wick is the chemical change

1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.

It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
because of the digestions system of the candle is visible
The melting of the wax is a physical change. The burning the of wick is the chemical change
because it can
it doesn't matter how high it is, if its burning, its a chemical change
Nope. A chemical change becuase of the reaction from the heat.
