What happens to the gibbs free energy term when a chemical reaction is reversed?

1 answer:

4 0

<span>When a chemical reaction is reversed the gibbs free energy has a decrease in temperature which effects the system. It is important that we test all systems before the chemical reaction is reversed so that the free energy is not lost. We want to test the temperature prior to results.</span>

Explain the relationship between the mole, particles, grams, and Liters.

Mamont248 [21]

Answer:A mole is an arbitrary number of molecules in a single unit - refer to avogadro's number. Essentially, 1 mole is 6.022x10^23 molecules for ALL molecules or atoms, however one must remember that not all atoms/molecules are the same size, this is where mass comes into play. When you measure out 2 grams of carbon powder, there will be a lot more molecules present than if you weighed out 2 grams of thorium powder; this is because carbon is much smaller - kind of like a car filled with clowns, one given car can hold a lot of small clowns but only a few big ones; so the same volume is occupied but the amount of substance (clowns) varies on their own size. The arbitrary mass (relative to the hydrogen atom) for a molecule is the sum of its atomic components' atomic masses; e. g. C2H6's will have 2x12.00 (carbon) + 6x1.01 (hydrogen) = ~30 grams / mole.

Acid base reaction is called nuetralization reaction why?

Lesechka [4]

Answer:

Explanation:

You have an acid that is acidic or a base that is basic. When you mix the two, they form water (assuming those are bronsted-lowry acids and bases) which is neutral.

For each of the salts below, match the salts that can be compared directly, using Ksp values, to estimate solubilities.

Anni [7]

Answer:

1 - Salts required that can be compared directly, using Ksp values, to estimate solubilities for copper (II) sulfide are - $CaSO_3$ (Option b) , $BaCrO_4$ (Option c) and $CaS$ (Option d)

2 - Salts that can be compared directly, using Ksp values, to estimate solubilities for zinc hydroxide are - $Mg(OH)_2$ (Option a)

Explanation:

$K_s_p$ values can be used to compare the solubility of salts that produce ions in a 1:1 ratio.

$CuS$ {copper (II)sulfide} dissociates with ions in ratio 1:1 .

Because the salts $CaSO_3$ , $BaCrO_4$ and $CaS$ have a 1:1 ion ratio, the solubilities of options b, c, and d can be compared to salt 1.

$K_s_p$ Values can be used to compare the solubility of salts that produce ions in a 1:2 or 2:1 ratio.

2. $Zn(OH)_2$ dissociates into ions in ratio 1:2 .

Because the ions in the salt $Mg(OH)_2$ are in a 1:2 ratio, the solubility of salt 2 can be compared to that of salt 'a'.

Hence , Salt 1 is matched with options b , c , d.

Salt 2 is matched with option a.

Do x-rays travel slower than infrared

OleMash [197]

No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.
