What happens at the anode in an electrolytic cell?

Chemistry
1 answer:
Llana [10]3 years ago
7 0

Answer:

D. Oxidation

Explanation:

In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.

A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).

In which species does sulfur have the highest oxidation number? s8 (elemental form of sulfur) h2s so2 h2so3 k2so4?
Mashutka [201]
There are rules to assigning conventional oxidation numbers to some elements. For those unspecified, you can solve them. This is how you solve it.

*S8. Since this is in elemental form, its oxidation number is assigned as 0.

*H2S. H is assigned with +1. Since the compound is neutral, the overall charge is 0. So,
2(+1) + x = 0
x = -2
The charge of S here is -2.

*SO₂. O is assigned with (-2). Using the same procedure,
x + 2(-2) = 0
x = +2
The charge of S here is +2.

*H₂SO₃.
2(+1) + x + 3(-2) = 0
x = +4.
The charge of S here is +4.

*K₂SO₄. K is assigned with +1. 
2(+1) + x + 4(-2) = 0
x = +6
The charge of S here is +6.

<em>The S with the highest oxidation number is the one in K₂SO₄.</em>

There are no negative consequences to using nuclear energy.
Tomtit [17]

Answer:

False

Explanation:

In Nuclear plants accidents such as explosions can occur which may lead to loss of life or severe injuries.

Nuclear energy production does not produce emissions but it produces radioactive waste which have to be stored adequately to prevent pollution. Since nuclear waste cannot be destroyed, measures have to be taken to adequately store the waste.

If the nuclear plant is being attacked, it can be used as a nuclear weapon to create disaster

What happens for a star to enter old age?​
Talja [164]

Answer:

Because the interstellar medium is 97% hydrogen and 3% helium, with trace amounts of dust, etc., a star primarily burns hydrogen during its lifetime. A medium-size star will live in the hydrogen phase, called the main sequence phase, for about 50 million years. Once hydrogen fuel is gone, the star has entered “old age.”

HCI+CaCO3=CaCl2+H2O+CO2<br>​
Nookie1986 [14]

Answer:

2 HCl + CaCO3  = CaCl2 + H2O + CO2

Explanation:

On the right side we have 2xCl, to get the same amount we will multiply HCl on the left side by 2.

This will give us 2xH on the left side; we also have 2xH on the right side ( in H2O).

On both sides we have 1x Ca; 1x C.

On the left side we have 3XO (in CaCO3), on the right side we have 1O in H20 and 2xO in CO2, so 3x O on the right side as well.

The reaction is balanced.

At what temperature (hot or cold) can we dissolve a gas in a solution
professor190 [17]

Depends on the gas and grams of solute. If you were able to give me a gas i would be able to help you but i cannot without the gas or chemical makeup.
