In a combustion reaction, pentane (molar mass (MM) = 72.17 g/mol) burns, in the presence of oxygen (MM = 32.00 g/mol), to produc

e carbon dioxide (MM = 44.01 g/mol) and water (MM = 18.02 g/mol).
The balanced reaction is shown here: C5H12 (l) + 8 O2 (g) à 5 CO2 (g) + 6 H2O (g)



If 4.0 mol of O2 is available, what is the maximum number of moles of water that can be produced (AKS 4f)?

A.
3.0 mol

B.
4.0 mol

C.
5.0 mol

D.
8.0 mol

E.
2.0 mol

What mass of copper is deposited when a current of 10.0a is passed through a solution of copper(ii) nitrate for 30.6 seconds?
asambeis [7]
Data Given:

Time = t = 30.6 s

Current = I = 10 A

Faradays Constant = F = 96500

Chemical equivalent = e = 63.54/2 = 31.77 g

Amount Deposited = W = ?

Solution:
             According to Faraday's Law,

                                          W  =  I t e / F

Putting Values,
 
                            W  =  (10 A × 30.6 s × 31.77 g) ÷ 96500

                            W  =  0.100 g

Result:
           0.100 g of Cu
²⁺ is deposited.

What volume of oxygen is needed to react with 20cm3 of ethane?
Anna71 [15]

Answer:

The reaction states that 2 moles of ethane react with 7 moles of oxygen. At standard temperature and pressure conditions (STP), each mole of gas occupies a volume of 22.4 liters. Therefore, 2 moles of ethane occupy liters, and 7 moles of oxygen occupy liters. In other words: 6 liters.

Explanation:

I hope it helps you
