Answer: 3CO_2+4H_2O

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

The balanced chemical reaction will be:

C_3H_8+5O_2 \rightarrow 3CO_2+4H_2O

The following redox reaction is conducted with [Al3+] = 0.12 M and [Mn2+] = 1.5 M.
Ronch [10]

Answer:

0.47V

Explanation:

2 Al(s) + 3 Mn2+(aq) → 2 Al3+(aq) + 3 Mn(s)

n= 6 ( six moles of electrons were transferred)

Q= [Red]/[Ox] but [Red]= 1.5M, [Ox] = 0.12 M

Q= 1.5/0.12= 12.5

From Nernst equation:

E= E°cell- 0.0592/n log Q

E°cell= 0.48 V

E= 0.48 - 0.0592/6 log (12.5)

E= 0.47V
