Directions: c = 299,792,458 m/s Little Boy was the atomic weapon dropped on Hiroshima toward the end of WWII. It had a yield (energy release) of 15,000 tons of TNT or 6.27E13 Joules. How much mass went “missing” when it detonated?

B

Explanation:

Strong linkages—called covalent bonds—hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms—in this case, oxygen and hydrogen—share electrons with each other.

The strong electrostatic attraction between adjacent cations and anions is known as an ionic bond. The most common example of an ionic compound is sodium chloride NaCl, better known as table salt. Unlike covalent compounds, there is no such thing as a molecule of an ionic compound.
