Answer:
Here is the complete statement: The overall change in enthalpy of a reaction depend ONLY ON REACTANTS AND THE PRODUCTS.
Explanation:
Change in enthalpy of a chemical reaction refers to the heat change that is associated with a chemical change when the pressure is held constant. Generally, chemical reaction involves the breaking of chemical bonds in the reactants and the formation of new chemical bonds in the products. The breaking and forming of bonds involve heat change; the amount of heat that is given off and absorb in each chemical reaction depend on the type of reactants and products that are involved in the chemical reaction.
Explanation:
The gravitational force between two objects is given by :
Where
G is universal gravitational constant
d is the distance between two masses
The gravitational force is inversely proportional to the distance between objects. It means when the distance between objects increases, gravitational force decreases and vice versa. To decrease the gravitational force between two objects, distance must increase.
