One atom is different from another atom if they have different numbers of protons in their nuclei.
The given chemical reaction is:
Δ∑BE(reactants)-∑BE(products)
= {(941 kJ/mol) + (3 * 242 kJ/mol)} -[{2*(3*200 kJ/mol)}]
= 467 kJ/mol
Calculating the change in heat when 85.3 g chlorine reacts in the above reaction:
Moles of chlorine =
= 1.20 mol
Heat change when 1.20 mol chlorine reacts
=
Answer: Weight is the measure of the force of gravity
Explanation:
Weight is a measure of the force of gravity on a physical object and is measured in newtons. The weight of a bird of mass 15 g varies with the magnitude of the gravitational force acting on it and would be considerably different if measured on the Moon, for example, instead of on Earth.
