Match each substance with the correct designation for the equation HSO3- + CH3NH2 <=> SO32- + CH3NH3+ HSO3- CH3NH2 SO32- C

Zanzabum

Answer:

$HSO_3^-$ : conjugate acid of $SO_3^{2-}$

$CH_3NH_2$ : conjugate base of $CH_3NH_3^+$

$SO_3^{2-}$ : conjugate base of $HSO_3^-$

$CH_3NH_3^+$ : conjugate acid of $CH_3NH_2$

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

$HSO_3^-+CH_3NH_2\rightleftharpoons SO_3^{2-}+CH_3NH_3^+$

Here in forward reaction $CH_3NH_2$ is accepting a proton, thus it is considered as a base and after accepting a proton, it forms $CH_3NH_3^+$ which is a conjugate acid.

And $HSO_3^-$ is losing a proton, thus it is considered as an acid and after loosing a proton, it forms $SO_3^{2-}$ which is a conjugate base.

Similarly in the backward reaction, $CH_3NH_3^+$ is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms $CH_3NH_2$ which is a conjugate base.

And $SO_3^{2-}$ is accepting a proton, thus it is considered as a base and after accepting a proton, it forms $HSO_3^{-}$ which is a conjugate acid.

Which ionic compound would you expect to have the highest melting point? a. Al-N b. Fe-O C. W-C

Elza [17]

Answer:

b. Fe-O

Explanation:

A way to predict melting points for ionic compounds is with electronegativity.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

The most electronegativity difference (E.D.), the highest melting point, thus:

E.D. Al-N = 3,0 - 1,6 = 1,4

E.D. Fe-O = 3,5 - 1,8 = 1,7

E.D. W-C = 2,5 - 1,7 = 0,8

The most electronegativity difference is from Fe-O, thus, this ionic compound will have the highest melting point.

I hope it helps!

In an experiment, onion plants of different ages were exposed to various amounts of caffeine to determine the effect of caffeine

VladimirAG [237]

A. is definitely true. The age of the plants and the amount of caffeine are two variables. The experimenter should have used only plants of the same age in order to determine the effect of caffeine.
b. is wrong. The amount of caffeine used was a variable.
c. is wrong. Temperature, water, and light were constants.
d. is wrong. The statement is a hypothesis that the experiment is trying to prove
