Opportunity cost refers to choosing one option over the others and live with the impact and consequence of that choice
Explanation:
All business owners come to experience this opportunity cost and would be left with the option to choose one aspect over the other and they would be ready to face the consequences. If you are a business owner you may ask yourself a question,' what choice am I choosing and will it be profitable if I select this choice over the other?'. This decision can be expressed in terms of opportunity cost.
Opportunity cost can be calculated by what you are sacrificing divided by what you are gaining. Money, time and effort are the three important factors which when sacrificed at the right time in right manner may gain any business owner, but the loss of any of these factors is what determines the opportunity cost.

Answer:
The total mass of materials present after a chemical reaction is the same as the total mass before the reaction
Explanation:
The Mass Conservation Act or the Conservation Matter Act proposed by Lavoisier postulates that: "The sum of the masses of the reactant substances is equal to the sum of the masses of the reaction products."
To reach these conclusions, Lavoisier used precise scales involving various elements in sealed containers. The total masses of the elements did not vary before (reactants) and after the reaction (products), remaining constant. Note that if he performed his experiments in an open environment there would be a loss of mass as the substance would react with air.
In this case, if we look at an iron that over time reacts with air (resulting in rust), we notice the variation in its initial mass. That is, it becomes larger after contact between them as it has the mass of iron and the mass of air.
Thus, we can state that the law of conservation of mass states states that the total mass of materials present after a chemical reaction is the same as the total mass before the reaction.
