Q. Which type of radioactive decay can pass through the body?
A. Gamma Rays
<span> the electron configuration for the manganese atom [Ne]3s</span>²
mr oxygen= 16. 16 x 3= 48
mr Al2O3= 27 + 27 + 48= 102
(48/102) X 100%= 47.05% oxygen
I am pretty sure the answer is D. That the patterns of a polarity matched up on both sides.
Answer:
Approximately 0.39 g or 0.4 g if you're rounding up
Explanation:
15/3.82 = 3.92
Let's round that up to 4
That means 15 days is around 4 half lives
4 half lives means 1/16 of the original mass will be left
25/16 = 0.390625
