the half-life of chromium-51 is 28 days, if the sample contained 350- grams how much chromium would remain after 3 half lives?

air quality

poor drinking water

and heavy polution

can lead to poor health

6.4 cm (max) - 25 cm (min)

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
