During Photosynthesis , Plants Transforms Light Energy Into Chemical Energy .
I rushed to the door to see what loud noise i heard, I seen a strange man standing on top of a body. As I screamed loudly, he started rushing towards me. ... He then began to slice my neck and I started to bleed out and collapsed on my front door. I suddenly woke up and realized it was all a dream, I went back to sleep.
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:
Answer:
Periods on the periodic table of elements
Explanation:
In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. (See also The Periodic Table: Metals, Nonmetals, and Metalloids.) In each period (horizontal row), the atomic numbers increase from left to right.
