Answer:

It's groundwater becomes contaminated.

Explanation:

More than 94% of the coal ash ponds in the United States are unlined. Almost all of them are contaminating groundwater with toxins above levels that the U.S. Environmental Protection Agency deems safe for drinking water.

Given: 4Na + O2 → 2Na2O In this chemical reaction, how many moles of Na2O will be produced if 2.90 moles of Na react completely?
crimeas [40]

Since we already have the balanced equation, we know that the ratio between Na:Na_{2}O is 4:2 respectively.

So then we can set up a proportion to find the number of moles produced when 2.90 moles of Na react completely:

\frac{4mol_{Na}}{2mol_{Na_{2}O}} =\frac{2.90mol_{Na}}{xmol_{Na_{2}O}}

Then we cross multiply and solve for x:

4x=5.8

x=1.45

Therefore, we know that when 2.90 moles of Na react completely, there are 1.45 moles of Na_{2}O that are produced.
