Answer:
6.02×10^23 atoms
Explanation:
Avogadros constant is a number that states the amount of atoms in one mole of a substance which is 6.02×10^23 to 3 significant figures.
The
equilibrium constant is a value which represents the equilibrium of a reaction.
It is a reaction quotient when the reaction reached equilibrium. The reaction in the system is expressed as:
<span>H2 + I2 = 2HI
we express Keq as follows:
Keq = [HI]^2 / [H2] [I2]
Where the terms represents the concentrations of
the substances involved. THe concentrations are as follows:</span>
<span>H2 = 0.763 ( 1 / 18.02) / 3.67 = 0.0115 M</span>
<span>I2 = 96.9 ( 1 / 253.8) / 3.67 = 0.1040 M</span>
<span>HI (at equilibrium) = 90.4 ( 1 / 127.91) / 3.67 = 0.1956 M</span>
<span>
By the ICE table, we can calculate the
equilibrium concentrations,
H2 I2 HI
I 0.0115 0.1040 0
C -x -x +2x
-----------------------------------------------------------
E 0.0115-0.0963 0.1040-0.0963 0.1926 ===> x = 0.0963
Keq = (</span>0.1926<span>)^2 / (0.0077) (0.0848)
Keq = 56.81</span>
<span>The chloroplasts.

Answer:
Fluorine
Explanation:
Fluorine has 9 total electrons. The first two are in the 1s level, and the remaining electrons are on the outer level of the atom, with 2 in the s level and 5 in the p level. The electron configuration is 1s2 2s2 2p5.
