How many moles make up 5.7491x1025 molecules of Dinitrogen pentoxide (N2O5)?
pav-90 [236]

Answer:

<h2>95.5 moles</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{5.7491 \times  {10}^{25} }{6.02 \times  {10}^{23} }  \\

We have the final answer as

<h3>95.5 moles to 3 sig. figures</h3>

Hope this helps you

When calcium and chlorine react to form calcium chloride, which substance is reduced? *
zhannawk [14.2K]

<u>Answer</u>:-

When the reaction takes place Ca is reduced or is an oxidizing agent.

Reaction:

Ca + 2Cl =CaCl2

Note: There is a +2 charge on Ca(Calcium) and -1 charge on each Cl-atom(Chlorine atom) hence the charges are cancelled. Therefore, the total charge on the whole compound is zero.

Explanation:-

• Reduction: gain of electron/electrons

gain of hydrogen

loss of oxygen

Oxidation: gain of oxygen

loss of hydrogen

loss of electron/electrons.

• Oxidizing agent/reduced

Reducing agent/oxidized

• The molecule that is oxidized loses an electron and the molecule that is reduced gains the electron that was lost by the oxidized molecule.
