Write a balanced equation for the complete combustion of propane, C3H8 . Do not enter phase symbols. Enter the alkane formula as
Anastaziya [24]
Answer:

C3H8 + 5O2 => 3CO2 + 4H2O

Explanation:

Hydrocarbon combustion is the reaction between a hydrocarbon and O2 producing CO2 and water.

C3H8 + O2 => CO2 + H2O

First we balance the C and H.

C3H8 + O2 => 3CO2 + 4H2O

Now we balance O for the answer!

C3H8 + 5O2 => 3CO2 + 4H2O

If 5 grams of hydrogen reacted with 40 games of oxygen to form water, how much of water would be formed?
GREYUIT [131]
2H₂ + O₂ = 2H₂O

n(H₂)=m(H₂)/M(H₂)
n(H₂)=5g/2.0g/mol=2.5 mol

n(O₂)=m(O₂)/M(O₂)
n(O₂)=40g/32.0g/mol=1.25 mol

H₂ : O₂ = 2 : 1

2.5 : 1.25 = 2 : 1

n(H₂O)=n(H₂)=2n(O₂)=2.5 mol

m(H₂O)=n(H₂O)M(H₂O)

m(H₂O)=2.5mol*18.0g/mol=45.0 g

Aluminum sulfate reacts with barium chloride to form the insoluble compound, barium sulfate. The reaction proceeds according to
Kaylis [27]

Answer: BaCl_2 is the limiting reagent and Al_2(SO_4)_3 is the excess reagent.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of aluminium sulphate}=\frac{150g}{342.15g/mol}=0.438moles

\text{Moles of barium chloride}=\frac{200g}{208.23g/mol}=0.960moles

The balanced chemical reaction is:

Al_2(SO_4)_3+3BaCl_2\rightarrow 2AlCl_3+3BaSO_4  

According to stoichiometry :

3 moles of BaCl_2 require = 1 mole of Al_2(SO_4)_3

Thus 0.960 moles of BaCl_2 will require=\frac{1}{3}\times 0.960=0.320moles  of Al_2(SO_4)_3

Thus BaCl_2 is the limiting reagent as it limits the formation of product and Al_2(SO_4)_3 is the excess reagent as it is left.
