WebThe rate at which a chemical substance or an element undergoes a chemical reaction is known as reactivity. The electrons between the elements are shared, or the elements lose or gain the electrons. The higher the reactivity of the element, the easier it is to combine. Hence the electronegativity and the ionisation energy determine a chemical ... WebStoichiometry (/ ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i /) is the relationship between the quantities of reactants and products before, during, and following chemical reactions.. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of …
