Consider the following voltaic cell:(j) In which direction do anions within the salt bridge move to maintain charge neutrality?

Chemistry

aniked [119]1 year ago
7 0

In order to maintain neutrality, the negatively charged ions in the salt bridge will migrate into the anodic half-cell. A similar (but reversed) situation is found in the cathodic cell.

<h3>What purpose does a salt bridge serve in an oxidation process?</h3>

Anions (negatively charged particles) are added to the solution of the oxidation half of the cell by the salt bridge, and cations (positively charged particles) are added to the solution of the reduction half of the reaction. 

<h3>What purpose does the salt bridge serve in a galvanic cell?</h3>

For instance, KCl, AgNO3, etc. In a galvanic cell, such as a voltaic cell or Daniel cell, salt bridges are typically used. A salt bridge's primary job is to assist in preserving the electrical neutrality of the internal circuit. Additionally, it aids in keeping the cell's response from reaching equilibrium.

The energy gap between the valence band and the conduction band in the widely-used semiconductor gallium arsenide (GaAs) is Δ =
stira [4]

Answer:

n_e = 8.139 *10^6

Explanation:

Given that;

The energy gap between the valence band and the conduction band in the widely-used semiconductor gallium arsenide (GaAs) is Δ = 1.424 eV.

So; that implies that:

\delta \ E = 1.424 \ eV

Suppose that we consider a small piece of GaAs with 1020 available electrons, -- This is taking about the numbers of electrons used which is :

n_i = 10^{20} \ electrons

Temperature is given as:

T = 274.15 \ K

Number of electrons can be calculated by using the formula;

n_e = n_i*e^-^{\frac{\delta E }{2 K_B*T}}

n_e = 10^{20}*e^-^{\frac{1.424}{2*8.617*10^{-5}*274.15}}

n_e = 8.139 *10^6

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O
algol13

Answer:

x = 4.5

4.5 moles of C2H6  is required to produce 13.5 moles of H2O

Explanation:

Given equation is :

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

if it requires 2 moles of C2H6 to produce 6 moles of H2O

then x moles of C2H6 is required to produce 13.5 moles of H2O

Using unitary method for solving, we get

x = 13.5 x 2 / 6

x = 13.5 / 3

x = 4.5

Therefore, 4.5 moles of C2H6  is required to produce 13.5 moles of H2O
