Question 13 of 16

Chemistry
1 answer:
Tanzania [10]3 years ago
8 0

Answer:

\rho =8.50g/cm^3

Explanation:

Hello,

In this case, due to the volume difference caused by the addition of the metal, one could notice that the volume of the metal is:

V_{metal}=9.84cm^3-6.85cm^3=2.99cm^3

In such a way, given the mathematical definition of density, it turns out:

\rho =\frac{m}{V}=\frac{25.4253g}{2.99cm^3}\\\\\rho =8.50g/cm^3

Regards.

What is the standard reduction potential,E, for the half-reaction Zn2+(aq)+2e- -> Zn(s)?
Tatiana [17]

Answer:

E = -0.76 V

Explanation:

The potential between the anode and the cathode is called standard reduction potential. It gives the tendency of the species to get reduced.

The given half reaction is :

Zn^{2+}(aq)+2e^{-}\rightarrow Zn(s)

Zn²⁺ is the reduced form of Zn.

It is a stronger reducng agent.

Its standard reduction potential (E) has a sandard value.

E = -0.76 V

Hence, the correct option is (c).
