Although each famous crater looks different, they have the same basic circular shape. Visit the Rio Cuarto craters in Argentina

(South America). Zoom in to see these oval-shaped craters.
What is the controversy surrounding these craters? What do you think?
Chemistry

Answer:

The controversy behind this craters is that thanks to the angle of the object's impact they could be habitable. Also, they could study them more.

Explanation:

The reason behind this answer is that majority of craters have an angle of impact of aorund45º. While the craters in the province of Cordoba, Argentina have an angle of impact of 15º. MAking them really plain, so they could be habitable for several species. Also, the materials found in the place suggest nothing more than quartz, so they represent no danger to the inhabitants, humans, or not. But more importantly that they have only received one major research study. Instead of a big variety, and they could be studied with more detail.

The pH of 0.10 M solution of an acid is 6. What is the acid dissociation constant of the acid?
svlad2 [7]

Answer: Dissociation constant of the acid is 10^{-11}.

Explanation: Assuming the acid to be monoprotic, the reaction follows:

                         HA\rightleftharpoons H^++A^-

pH of the solution = 6

and we know that

pH=-log([H^+])

[H^+]=antilog(-pH)

[H^+]=antilog(-6)=10^{-6}M

As HA ionizes into its ions in 1 : 1 ratio, hence

[H^+]=[A^-]=10^{-6}M

As the reaction proceeds, the concentration of acid decreases as it ionizes into its ions, hence the decreases concentration of acid at equilibrium will be:

[HA]=[HA]-[H^+]

[HA]=0.1M-10^{-6}M

[HA]=0.09999M

Dissociation Constant of acid, K_a is given as:

K_a=\frac{[A^-][H^+]}{HA}

Putting values of [H^+],[A^-]\text{ and }[HA] in the above equation, we get

K_a=\frac{(10^{-6}M).(10^{-6}M)}{0.09999M}

K_a=1.0001\times 10^{-11}M

Rounding it of to one significant figure, we get

K_a=1.0\times 10^{-11}M\approx 10^{-11}M

Why are ionic compounds solids
enot [183]

Answer: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points.
