Yes, people should be concerned because plaque buildup might cause your breath to smell bad, or cause your teeth to look very yellow, consider brushing your teeth and using mouth wash daily and don’t drink or eat unhealthy foods that will cause your teeth to look bad. plaque buildup might also cause damage to the stomach and maybe affect when you have to use the restroom.

Where is most of the high-level waste stored in the United States
Anna007 [38]

The correct answer is number 5) at the nuclear reactor site.

Most of the high-level waste stored in the United States is at the nuclear reactor site.

Just people who specialize in the radioactive waste can handle this risky procedure because high-level radioactive waste needs treatment by the experts to truly isolated from the biosphere. Radioactive plants keep the waste deep underground because nobody wants another accident like the one that happened in Chernobyl on April 26, 1986.

The other options of the question were 1) the ocean. 2) mountain peaks. 3) volcanic fissures. 4) salt mines.

What is the volume in liters of 321 g of liquid with a density of 0.84 g/mL
Rasek [7]
Density is weight by volume.   

First.  If you divide the weight by density you can find the volume

Second you must convert the ML in to Liters.

\frac{321 \frac{g}{1}}{0.84 \frac{g}{mL}} = \frac{321(g)(mL)}{0.84g}=\frac{321mL}{0.84}=382.14mL

1L=1000ml

\frac{1L}{1000mL}

(382.14mL)( \frac{1L}{1000mL})= \frac{(382.14mL)(L)}{1000mL} =\frac{382.14L}{1000}=0.38214L

0.38214 Liters.
