The balanced chemical
reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of propane gas to be burned. This will be
our starting point.
<span>38.95 </span><span>g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1
mol C3H8)(32 g O2 / 1 mol O2) =141.32 g O2
Therefore, the reaction consumes approximately 142 grams of oxygen gas.</span>
Answer:
Water is added to a concentrated solution of sodium thiosulfate to dilute it.
Explanation: Water is a universal solvent. It has the capability to dissolve many substances in it. When water is added to a solution, the concentrated solution can be diluted. Dilute solution means the presence of water in high amount and solute quantity is very low.
