How many moles of electrons are transferred when 2.0 moles of aluminum metal react with excess copper(II) nitrate in aqueous sol
mojhsa [17]

Moles of electrons:

The moles of electrons that are transferred are 12F

A balanced equation:

2 moles of Aluminium metal react with excess copper(II) nitrate.

2Al + 3Cu{(NO_3)}_2  \rightarrow 2Al{(NO_3)}_3 +3 Cu

Given:

Moles of Aluminium = 2

As Aluminium goes from 0 to +3 oxidation state

Al \rightarrow Al^{3+} + 3e^-

And copper goes from +2 to 0

Cu^{2+} + 2e^-\rightarrow Cu

On balancing the number of electrons we get:

For 1 mole of Al 6e^- is required.

Therefore for 2 moles of Al,

Total (2\times6)F mole of electrons

Where F= Faraday's constant= 96500 C

So, 12F moles of electrons are transferred.

If a sample containing 2.00 mL of nitroglycerin (density=1.592g/mL) is detonated, how many total moles of gas are produced?
fgiga [73]

The overall balanced chemical reaction for this is:

Detonation of Nirtoglycerin <span>
4 C3H5N3O9 --> 12 CO2 + 6 N2 + O2 + 10 H2O </span>

 

Therefore:

2.00 mL x 1.592 g/mL = 3.184 g <span>
3.184 g / 227.1 /mol = 0.0140 mol nitroglycerin 
4 moles --> 12 + 6 + 1 + 10 = 29 moles of gas 
<span>0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol) </span></span>

Toluene, c6h5ch3, is a liquid compound similar to benzene, c6h6. it is the starting material for other substances, including tri
babymother [125]
Toulene = 35.6 g 
Benzene = 125 g = 0.125 kg
 Molecular weight of Toluene C6H5CH3 = 92.1g/mol
 Moles of toulene = 35.6 g / 92.1 g/mol = 0.3865 mol

 Now the molarity of the toulene in the given solution = 0.3865 / 0.125 = 3.092 m 
 Molarity of C6H5CH3 = 3.092 m
