14C has a half-life of 5,370 years. Assume that a sample of organic material contains 4.0 grams of 14C. Three half-lives would be?
The amount of the organic material that would remain after three half-lives has elapsed is 0.5 g
Data obtained from the question Half-life (t½) = 5370 yearsOriginal amount (N₀) = 4 gNumber of half-lives (n) = 3Amount remaining (N) = ?How to determine the amount remaining
The amount remaining after 3 half-lives has elapsed can be obtained as follow:
N = N₀ / 2ⁿ
N = 4 / 2³
N = 4 / 8
N = 0.5 g

How can dry ice literally burn you?
Does it burn everyone if handled with bare hands?
Answer:
While dry ice looks like it would be cold, it's extremely dangerous to the touch and can cause severe burns.
Explanation:
Dry ice is frozen carbon dioxide. It has the very nice feature of sublimation as it melts, it turns directly into carbon dioxide gas rather than a liquid. If you ever have to handle dry ice, you want to be sure to wear heavy gloves, because a block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). The super-cold surface temperature can easily damage your skin if you touch it directly. It's actually a lot like if you were to touch the handle of a hot pot or pan without an oven mitt.
