The answer is 8 :)
All nobel gases have 8 outer electrons.
Reactivity of non-metals depend on their ability to gain electrons. So, smaller is the size of a non-metal more readily it will attract electrons because then nucleus will be more closer to valence shell. ... Hence, Br is the non-metal which will be more reactive than At.
Because an egg is an entire biological structure, made up of a mixture of chemicals rather than a single pure chemical compound, there is no one chemical formula to describe it. However, the basic structure and chemistry of an egg is highly conserved and varies little from species to species.
The balanced chemical reaction is:
N2 + 3H2 = 2NH3
We are given the amount of ammonia formed
from the reaction. This is where we start our calculations.
0.575 g NH3 (1 mol NH3 / 17.03 g NH3) (3 mol
H2 / 2 mol NH3) ( 2.02 g H2 / 1 mol H2) = 0.10 g H2
