What happens at the anode in an electrolytic cell?
Llana [10]

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).

T or F: Lone pairs around the oxygen atom of a water molecule play no role in determining its molecular geometry?
Mama L [17]

Answer:

Explanation:

They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.

Define cation and anion. In which case are electrons gained? Lost?
inn [45]

Explanation:

A cation is a positively charged ion.

An anion is a negatively charged ion.

  • In a cation, electrons are usually lost
  • In an anion, electrons are usually gained.

In an atom, the balance between the number of protons and electrons determine whether they become an anion or cation.

Protons are positively charged particles.

Electrons are negatively charged

 When an atom gains electrons, the number of electrons becomes more than that of protons. This leaves a net negative charge on the atom and it makes an anion.

 When an atom loses electrons, the number of protons becomes more than that of electrons. This leaves a net positive charge on the atom and makes a cation.
