Cobalt-59 and Cobalt-60 differ in that they have different mass number which means they have different number of neutrons. Isotopes are atoms of the same element with similar atomic number but different mass number. Cobalt-60, has a number of uses, which includes, being used to irradiate food sources as a method of preserving food, used in industrial radiography to detect structural flaws in metal parts among other uses.
Chemical equilibrium is theequilibrium state in which the concentrations of reactants andproducts is not changed with time. ... Theory Physical equilibrium includes the coexistence of two physical states inside the same closed system.Chemical equilibriums include equal rates of forward and backward reactions.
<u>mass of reactants = mass of products</u> best represents the law of conservation of mass
Explanation:
This is a law of thermodynamic that applies to chemical reactions. The mass of the reactants must equal to that of the products because energy/mass cannot be destroyed or created. This is why ideally, chemical reactions should be balanced to conform to this law.
