Answer:

Every planet in the solar system has seasons. Extraterrestrial seasons are hardly noticeable on some planets (Venus), mindbogglingly extreme on others (Uranus) and in some cases simply impossible to define (Mercury).

Answer:

Observe the other planet throughout the year. Look at the environment when the season changes to see what changes in the environment.

(b) Which solution has a higher percent ionization of the acid, a 0.10M solution of HC2H3O2(aq) or a 0.010M solution of HC2H3O2(

boyakko [2]

Answer: The percent ionization is higher for 0.010 M solution of $HC_2H_3O_2$

Explanation:

$HC_2H_3O_2\rightarrow H^+C_2H_3O_2^-$

cM 0M 0M

$c-c\alpha$ $c\alpha$ $c\alpha$

So dissociation constant will be:

$K_a=\frac{(c\alpha)^{2}}{c-c\alpha}$

a) Given c= 0.10 M and $\alpha$ = ?

$K_a=1.8\times 10^{-5}$

Putting in the values we get:

$1.8\times 10^{-5}=\frac{(0.10\times \alpha)^2}{(0.10-0.10\times \alpha)}$

$(\alpha)=0.013$

$\%(\alpha)=0.013\times 100=1.3\%$

b) Given c= 0.010 M and $\alpha$ = ?

$K_a=1.8\times 10^{-5}$

Putting in the values we get:

$1.8\times 10^{-5}=\frac{(0.010\times \alpha)^2}{(0.010-0.010\times \alpha)}$

$(\alpha)=0.041$

$\%(\alpha)=0.041\times 100=4.1\%$

The percent ionization is higher for 0.010 M solution of $HC_2H_3O_2$

What does a chemical bond results from a rearrangement of?

Dmitriy789 [7]

Atoms

Explanation:

Chemical bonds results from the rearrangement of atoms in a chemical species.

It deals with the various attractive forces joining chemical species togethe.

When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
This is made possible by the exchange or sharing of electrons.
The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
When atoms are re-arranged in compounds they lead to the production of chemical bonds.
