Is paper a physical or chemical change?
Litmus is a water-soluble mixture of different dyes. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic (i.e. alkaline) conditions, with the color change occurring over the pH range 4.5 - 8.3. Neutral litmus paper is purple in color. Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions the solution is red, and under basic conditions the solution is blue. So the litmus paper turning blue or red is a "Chemical Change".
How the law of conservation of mass applies to chemical changes?
As in all conservation laws, it means that mass (in this case) won't increase or decrease.In chemical reactions there is a stronger law, which can be quite useful: the total number of atoms OF EACH KIND won't change; thus, if at the start of a reaction you have, for example, three carbon atoms, two oxygen atoms, and four hydrogen atoms in total, at the end you'll have the same combination (three carbon, etc.).

Explain why burining a candle is a chemical cange wile melting wax is a physical change?
Can you recover the original material(s) after the change without using chemical means? Burning - no. What was once the wax (and wick) now have different chemical compositions that cannot be recovered other than by chemical means. Thus, it's a chemical change. Melting - yes. The wax can be recovered without using chemical means. The melted wax is allowed to cool down, and this is a physical change, so the recovery is by physical means. Thus, it's a physical change. Tip: how do you reverse a change? That's the type of change it is.
