<span>The reaction of a burning candle gives off heat and is an exothermic reaction. It does not absorb heat because it does not cool down its surroundings as the candle burns. The answer is the reaction of a burning candles gives off heat.</span>
Equations represents the law of conservation of mass is 2H₂O → 2H₂ + O₂
Law of conservation of mass stated that energy neither be created nor destroyed called as law of conservation of mass and as the same no of each atom present in the both side of the reaction this reaction represents the law of conservation of mass so in the equation 2H₂O → 2H₂ + O₂ the energy cannot be created nor destroyed water can form 2 mole of hydrogen and 1 mole of oxygen which form water

Answer:
Flammability.
Explanation:
Chemical properties of a substance are properties of a substance that occur in the chemical reactions in which it is involved. These are the basis for the classification of substances, such as metals, halogens, acids, alcohols, alkenes, arenes, etc. A class of substances is characterized by chemical properties common to that group. Differences in the chemical and physical properties of substances allow the substance to be identified, and the components of a mixture of substances to be separated and purified.
The chemical properties of a substance are its chemical stability, reactivity, oxidizability, acidity, bromine number, polymerisability, flammability, toxicity, etc. These can be determined by chemical exposure.
