The black swirly one, on the bottom right, is black hole. The one with rays coming out of it, the one next to the black hole, is super nova. Thats all I know im srry...
120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
12.042mL because the equation is 13.5/x=.892g/mL
*13.5 *13.5
---------------------
x=12.042
Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond. ... Naturally occurring graphite occurs in two forms, alpha and beta.
