Answer:
a resource that cannot be replenished in a short period of time.
Explanation:
Nonrenewable energy sources take thousands to millions of years to replenish. hence the "nonrenewable".

Answer:
ΔHrxn = [(1) -1675.5 ( kJ/mole) + (2) 0 ( kJ/mole)] - [(1) -824.3 ( kJ/mole) + (2) 0 ( kJ/mole)]
Explanation:
ΔHrxn = 2ΔHf (Al₂O₃) - ΔHf (Fe₂O₃)
Remember that for pure elements in their standard state of temperature and pressure by definition their standard heats of formation are zero.
ΔHrxn = 2(-1675.7) - (-824.3) kJ/mol
ΔHrxn = 2527 kJ/mol
Mass is calculated by using an objects inertia. Since inertia is a quality of matter that resists motion, we can apply an increasing force to an object until it accelerates.
Then, by measuring its acceleration we can now determine its mass using the simple equation F=m×a, except rewritten as m=Fa.
So we divide the force that we applied by the acceleration rate and we get the objects mass.
Without inertia this cannot be done.
∴ Answer is C
