Answer:
There are no options in this question, however, the equation can be provided. The answer is:
2Na + 2H2O --> 2NaOH + H2
Explanation:
This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:
Na + H2O --> NaOH + H2
From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.
We have;
2Na + 2H2O --> 2NaOH + H2
not really sure cuz this is biogeography and this not my field, but i think (C) is the correct answer (a biome may include multiple ecosystems that share a smaller climate).
