This is an incomplete question, here is a complete question.
The reduction of iron(III) oxide to iron during steel-making can be summarized by this sequence of reactions:
;
;
The net reaction is:
;
Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K be sure you use their standard symbols.
Answer : The equilibrium expression will be:
Explanation :
The intermediate reaction are:
(1) ;
(2) ;
The net reaction is:
;
Now we are multiplying reaction 1 by 3 and reaction 2 by 2 and then adding both the reaction we get the net reaction.
(1) ;
(2) ;
If the equation is multiplied by a factor of '2' or '3', the equilibrium constant will be the power of 2 or 3 of the equilibrium constant of initial reaction.
If the equations are added then the equilibrium constant of the reactions will be multiplied.
Thus the equilibrium expression will be:
The answer is C, number of molecules.
Answer:
It’s false
Explanation:
it could be true if the question mentioned alkaline solution
The answer is TRUE.
Energy is an extensive property, which means that it is in proportion to the amount of matter: more mass, more energy.
You can measure, for example, the internal energy per mol or per gram of several compounds or elements. then if you want to know the total internal energy of the system you have to multiply by the number of moles or grams, depending on the unit of the internal energy that you use.
Answer:
Sample Response: If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
Explanation:
its the sample response
