Answer:-
10.0
Explanation: -
The equation is
N2O4 = 2NO2.
Concentration of NO2 = [NO2} = 0.500 M
Concentration of N2O4 = [N2O4] = 0.0250 M
Keq is the equilibrium constant.
It is the ratio of the concentration of products raised to the stoichiometric coefficient of the product to the concentration of the reactants raised to the stoichiometric coefficient of the reactants.
The expression for Keq = [NO2] ^2 / [N2O4]
= 0.500^2 / 0.0250
= 10.0
Answer:
A. A galvanic cell generates electrical current, and an electrolytic cell uses electrical energy to cause redox reactions to occur.
Explanation:
A galvanic cell produces electrical energy through the conversion of chemical energy whereas the electrolytic cell carries out the conversion of the electrical energy/current supplied to it into chemical energy. The reaction that takes place in the galvanic cell is spontaneous which is responsible for the electrical energy that is produced. The redox reaction in the electrolytic cell is not spontaneous. Electrical energy has to be supplied to it in order to initiate the reaction.
Answer:
The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
Sorry, I don’t believe in Jesus or god etc but thnx???
