Nuclei differ in their stability, and some are so unstable that they undergo radioactive decay. The ratio of the number of neutrons to the number of protons in a nucleus (N/Z) correlates with its stability. Calculate the N/Z ratio for 146Sm.

Aluminum reacts with sulfuric acid to produce aluminum sulfate and hydrogen gas. how many grams of aluminum sulfate would be formed if 250 g h 2 so 4 completely reacted with aluminum? 2al( s ) + 3h 2 so 4 ( aq ) ? al 2 (so 4 ) 3 ( aq ) + 3h 2 ( g )
