Answer:
3.87 x 10^24
Explanation:
Simply multiply the moles by avogadros number
6.42 moles of H2O x 6.022 x 10^23 molecules/1 mole of H2O = 3.87 x 10^24 molecules of H2O
Halogen are the most reactive due to their electronic configuration
60 Grams are produced due to the fact that it may not produce more due to the certain capacity that varies on the size of the cube.
It would be a physical change. It’s still water just in a different physical form. If it was a chemical change, it would no longer be water. For example, when the ice melts back into water...it’s still water.
C. NO2 is covalent. Hope this helps!
