It would protect best against C) Alpha radiation, as Beta radiation is stopped by lighter metals such as aluminium, and Gamma radiation can only be stopped by heavier metals such as lead.
Well, since ammonia has the chemical formula NH3. Therefore the
relative atomic mass is 17 (14+(1)3). So 100 divided by 17, times 3
= 17.64705882352941g. I did this in order to figure out firstly,
how much the weight of 1 of the 17 nuclear particles, which make up
ammonia, would have to be present (in grams) for everything to be
in proportion to which would make 100g. Then by timesing it by 3
shows how much the 3 hydrogen atoms contributed in weight towards
the 100 grams. To prove that 17.64... is correct you can add
(100/(17) X (17-3).
Answer: fuel cells have a higher efficiency than diesel or gas engines. Most fuel cells operate silently, compared to internal combustion engines.
Explanation:
Answer:
Because even though nitric acid is obserdely strong, gold os the least reactive of all metals so it can not be reacted with.
