1.8x10^20 atoms x (1 mole / 6.022x10^23 atoms) = 3.0x10^-4 mole
Assuming that the reaction from A and C to AC5 is only
one-step (or an elementary reaction) with a balanced chemical reaction of:
<span>A + 5 C ---> AC5 </span>
Therefore the formation constant can be easily calculated
using the following formula for formation constant:
Kf = product of products concentrations / product of reactants
concentration
<span>Kf = [AC5] / [A] [C]^5 </span>
---> Any coefficient from the balanced chemical
reaction becomes a power in the formula
Substituting the given values into the equation:
Kf = 0.100 M / (0.100 M) (0.0110 M)^5
Kf = 6,209,213,231
or in simpler terms
<span>Kf = 6.21 * 10^9 (ANSWER)</span>
It’s aluminum because electrons and protons are basically the same thing just in different places on a electron cloud and the atomic number is 13 so I think it’s aluminum.
Answer:
Explanation:
<u>Chemical formulas for every compound:</u>
Potassium vapor => 
Molten soldium chloride => 
Molten Potassium chloride => 
Molten Sodium Metal => 
<u>The reaction will be as follows:</u>
This reaction is usually called displacement reaction in which an element displaces another element of a compund.

H3PO4 + H2O <--> H3O+ + H2PO4- Ka1= ([H3O+][H2PO4-])/[H3PO4])
H2PO4- + H2O <--> H3O+ + HPO4^2- Ka2= ([H3O+][HPO4^2-])/[H2PO4-])
HPO4^2- + H2O <--> H3O+ PO4^3- Ka3= ([H3O+][PO4^3-])/[HPO4^2-])
Ka1 >> Ka2 = almost all the H3O+ is formed in the first step.
Ka3 will only happen under very basic conditions.
