On-the-job experience typically enhances a person’s productivity in that particular job. If theperson’s salary increases to reflect increased experience but the additional experience has no relevance for other jobs, does this higher salary reflect an increase in opportunity cost or in economic rent?

Calculate the mass (g) of magnesium oxide produced when 500 g of magnesium reacts with oxygen in the air.
2Mg + O2 → 2MgO
Calculate the pH of an acetic acid solution at 3.20 x 10-4 mol/L (% ionization = 1.30%).
Determine the [H3O+(aq)] of a solution with a pH of 3.45.
Expressed in scientific notation, the answer is in the form a,b × 10–c.
red giant star becomes exhausted of nuclear fuel, the outer material is blown off into space leaving the inert Carbon. The remnant is known as WHITE DWARF.
the star is unable to generate heat when it runs out of hydrogen in its core leading to its contraction and expansion. It cools down and glows red. The helium fused into Carbon. The star is now a RED GIANT.
