HEY..
ANSWER.
Q1. In a chemical change the product are quite a different from the reactant therefore it cannot be normally reversed.
Q2. Chemical equation has to give balance to meet the requirements of the law of conservation of mass according to law in the total mass of reacting spaces taking part in the reaction in the same as that of the products formed since there is a direct relationship between the mass of the different species and their number it is always essential to balance the equation.
Q3. Because they differ in the arrangement of carbon atoms present and have different shapes that is why they involve different amount of heat just like carbon + oxygen is carbon dioxide + 3 93.5 Kelvin.
Q4. The milky nails of limestone is due to the formation of calcium carbonate which is the in the form of suspended particles when carbon gas is passed in excess the menace disappear due to formation of soluble calcium hydrogen carbonate .
Q5. No rusting of iron cannot take place in distilled water because it neither contains dissolved oxygen no carbon dioxide both are essential for the rusting of iron.
_________&______________.

first answer.. a chemical change be normally reversed this is because of the product forming during the chemical changes are very much different from the reacting materials.
