AB----> A + B
rate= k(ab)^2
by use of integrated second order rate law
1(/Ab)t = 1/AB)0 + Kt
t= time
k=constant
(AB)0 =initial concentration
(AB)t= final concetration
1/(ab)t= 1/1.5 + 0.20 x12.9 = 3.35
1/(ab)t = 3.25 multiply both side by ( ab)t
1= 3.25(ab)t divide both side by 3.25
(ab)t is therefore=0.308
The statement that would be held true for an acidic solution would be option C. The molarity or concentration of the hydronium ions would be more than that of the hydroxide ions. As the acidity of a solution increases as there is a greater amount of H+ or H3O+ ions present, within it. This is will give us a low pH and thus is quite acidic.
If the concentrations of the OH- and H3O+ are the same then the solution would be neutral, and if the opposite is true. The concentration of OH- is more than H3O+ than the solution would be basic.

Answer:
Becuse magnesium is a earth alkaline metal and oxygen is a nonmetal(read explanation)
Explanation:
Magnesium has 2 valence electrons where oxygen has 6 valence electrons. Magnesium has tendency to give electrons to oxygen and oxygen has tendency to gain electrons. They are both trying to complete their last shell to 8 which is called the octet rule. Because they both want to complete each other because of the reasons that I told they combine to be stanle atoms like noble gases.
