Answer:
Hydrogen is a very reactive element. It doesn't exist as a single atom in nature. Neither do any of the other binary nonmetals -- nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. They're too prone to react with something. They react with each other and form binary molecules because the binary molecules are more stable than single atoms (by a lot!). Compounds with other atoms are even more stable, so hydrogen reacts with oxygen to form water, and chlorine reacts with sodium to form table salt.
Explanation:
I believe it was Hiroshima. Followed by Nagasaki. Moscow was never bombed in my knowledge, and Auschwitz was a death camp, so it wasn't bombed.
She would divide that mass of each element by it molar mass the answer is C <span />
Answer:
The volume occupied by molecules becomes a significant part of the total volume.
Attractions between molecules cause a reduction in volume.
Explanation:
C is wrong. The masses of molecules are constant.
From start:
Joule, J, calorie,
Example 1: 120 J / 4.184 = 28.68 cal
Example 2: 1200 cal * 4.184 = 5020.8 J
