Some chemical changes can be reactive through another chemical change?
Answer: 12.5 moles NaNO3
Explanation: solution attached.
First balance predict the products
Na+ Mg( NO3)2 => Mg + NaNO3
Next balance the chemical equation
2 Na + Mg(NO3)2 => Mg + 2 NaNO3
Solve for the moles of Na
175 g Na x 1 mole Na/ 14 g Na
Next compare the mole ratios of Na and NaNO3 based from the balanced equation.
2 moles Na : 2 moles NaNO3
Answer:
the process of returning a land area to the condition it was in before humans used the land
Explanation:
Reclamation refers to the process of returning a disturbed ecosystem to its original status prior to the disturbance. Often times, the disturbance regimes that change the conditions of the ecosystem are created by humans.
<em>Reclamation is unlike reforestation in that the latter involves the process of planting trees in order to reestablish forest lands, not necessarily return the land to its previous status.</em>
Reclamations are often done to return lands to the original flora and fauna status before the disturbance regime.
