What mass of the excess reagent remains after the reaction is complete?
grams

We can't until we know what we are working with or on

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.

Different materials have  different abilities to transfer enegry

Because acidic elements release hydroxide ions, while bases release hydrogen ions.  mark
