In an electrolytic cell, which ion would migrate
Murljashka [212]

Answer:

Silver ion

Explanation:

In an electrolytic cell, the positive ions known as the cations migrate to the negative electrode, the cathode where they accept electrons to become discharged as neutral atoms. Also, the negative ions known as the anions migrate to the positive electrode, the anode, where they give up their electrons to become discharged as neutral atoms.

From the question above, the only positive ion among the options given is the silver ion, Ag+, therefore, it is the correct option.

How many moles are in 1.9 x 1046 atoms of chromium?
faust18 [17]

Answer:

<h2>3.156 × 10²² atoms</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1.9 \times  {10}^{46} }{6.02 \times  {10}^{23} }  \\  = 3.156 \times  {10}^{22}

We have the final answer as

<h3>3.156 × 10²² atoms</h3>

Hope this helps you
