Answer:
The Octet Rule says that atoms are most stable with a full outer shell of 8 electrons valence electrons.
The formula for Keq for the first chemical reaction with
given Keq is:
<span>Keq 1 = [ HI ]^2 / [ H2 ] [ I2 ]</span>
<span>While the formula for Keq for the 2nd is:</span>
<span>Keq 2 = [ HI ] / [
H2 ]^(1/2) [ I2 ]^(1/2)</span>
We can see that the coefficients in the reaction are
equal to the exponents in the equilibrium equation. Therefore if we divide the
whole reaction by 2, then that means we have to take the square root of the
equilibrium equation. Or in this case,
Keq 2 = sqrt (Keq 1)
Keq 2 = sqrt (794)
<span>Keq 2
= 28.19</span>
Answer:
a) 200 L of water. b) 3,2210(fifth to the power) kg
Explanation:
a) To reach toxic level of a person would have to drink 200 L of water. b) We need 3,2210 to the fifth power kg of fluride for 8,510 to the seventh power gal of water.
