A 100.0 g sample of Co-60 decays until only 12.5 g of it remains. Given
that the half-life of Co-60 is 5.271 years, how long did the decay take?

How many electrons does silver have to give up in order to achieve a sido noble gas electron configuration

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
