As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur. <span>During a chemical reaction, new substances are produced as existing bonds are broken, atoms are rearranged, and new bonds are formed.</span>
Its because of the static electricity.As we rub, the positive and negative charges are acquired by the plastic rod and duster.
If we bring paper bits near them, the charges possessed by the paper bits get attracted towards the charges in plastic rod.
Answer:
(a) and (b)
Both will follow the rule
This is due to property of charges.
As in case of gravitational potential energy as it increases as height increases.
In case of electrical potential energy it will increase as charges comes close.
Explanation:
have a good day:))
