Propane burns in oxygen to produce carbon dioxide and steam. The unbalanced equation for this reaction is: C3H8 + O2 → CO2 + H2O

NemiM [27]

Here is your answer

C3H8 + O2-----> CO2 + H2O

Balancing C atoms

C3H8 + O2------> 3CO2 + H2O

Balancing H atoms

C3H8 + O2------> 3CO2 + 4H2O

Balancing O atoms

C3H8 + $\bold{5}$ O2-------> $\bold{3}$ CO2 + $\bold{4}$ H2O

Hence the equation is balanced.

C. 49.8 grams of ki is dissolved in enough water to make 1.00 l of solution. what is the molarity?

taurus [48]

Hey There!:

Molar Mass KI => 166.003 g/mol

* number of moles:

n = mass of solute / molar mass

n = 49.8 / 166.003

n = 0.3 moles KI

Therefore:

M = n / V

M = 0.3 / 1.00

M = 0.3 mol/L

hope this helps!
