A particular voltaic cell operates with the reaction: Zn(s)+Cl2(g)--->Zn^2+(aq)+2Cl^-(aq) giving a cell potential of .853 V.
nadya68 [22]

Answer:

The amount of energy liberated will be 49.38 J.

Explanation:

The amount of energy liberated (gibbs free energy) can be calculated using the following equation:

ΔG° = -nFε

n: amount of moles of electrons transfered

F: Faraday's constant

ε: cell potential

20.0 g of Zn is equal to 0.30 mol.

Two electrons are transfered during the reaction.

Therefore, n = 2x0.30 ∴ n = 0.60

ΔG° = - 0.60 x 96.485 x 0.853

ΔG° = 49.38 J

Half-reaction for the reduction of liquid water to gaseous hydrogen in basic aqueous solution
Elena L [17]

Answer:

2H₂O (liq) + 2e⁻⇒ H₂ (g) + 2OH⁻ (aq)

Explanation:

In reduction-oxidation reaction two reactions take place, one is oxidation and the other is reduction reaction. In an oxidation reaction, there is the loss of an electron whereas in the reduction reaction there is gain of electron occus.

Reduction reaction occurs on the cathode, in a reduction of water there is gain of 2 electrons to gaseous hydrogen in basic aqueous solution. half-reaction for the reduction of liquid water to gaseous hydrogen in basic aqueous solution-

2H₂O (liq) + 2e⁻⇒ H₂ (g) + 2OH⁻ (aq)

Which type of substance is soft, has a low melting point, and is a poor conductor of electricity
In-s [12.5K]

Answer:

Covalent compounds have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound). Little energy is needed to break their bonds, therefore they have low meting points. Hope this is what you are looking for!

Calculate the rate constant, , for a reaction at 74.0 °C that has an activation energy of 86.4 kJ/mol and a frequency factor of
Lelechka [254]

The rate constant is 4.84 * 10^11 s-1.

From the Arrhenius equation;

k = Ae^-Ea/RT

k = rate constant = ?

A =  frequency factor = 4.99×1011 s−1

Ea = Activation energy = 86.4 kJ/mol

R = gas constant = 8.314 J/K/mol

T = Absolute temperature = 74.0 °C + 273 = 347 K

k = 4.99×10^11e^- 86.4/8.314 * 347

k = 4.84 * 10^11 s-1.

The rate constant is 4.84 * 10^11 s-1.

Why and how is mass an extensive property ?
defon
<span>An extensive property is a property that changes when the size of the sample changes. Examples are mass, volume, length, and total charge. An intensive property doesn't change when you take away some of the sample.</span>
