Answer:
2K + 2H2O → H2 + 2KOH
Explanation:
Find how many atoms you have on both sides then add 2 to both sides.
Reactant: Products:
K: 1+1=2 K: 1+1=2
H: 2+2=4 H: 3+1=4
O: 1+1=2 O: 1+1=2
Therefore it is balanced. Hope this helps
Answer:

Explanation:
First you should calculate the volume of a big sphere,so:



Then you calculate the volume of a small spehre, so:



Finally you subtract the two quantities:


1) reaction coordinate is : <span>b.the plot of the reaction progress as a function of time
2) </span>ΔG⁰ : <span>c.the free energy of the reaction
3) </span>ΔG⁺+ : <span>a.the higher point on the energy curve</span>
