Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.
Explanation: The given reaction is a type of combustion reaction.
Combustion reaction is a reaction in which a hydrocarbon reacts with oxygen gas to produce water and carbon dioxide gas.
For the reaction of pentane with oxygen, the balanced equation would be:

In the reaction, 1 mole of
reacts with 8 moles of
gas.
Thus giving us the mole ratio as
Oxygen : Pentane = 8 : 1
Answer:
Normally, it explains that matter cannot be created or destroyed. It demonstrates different chemical reactions that help show the different transformations of the matter but will never destroy it or create it.
<h2>Answer:</h2>
<em>Given data:</em>
1 kilogram = 1,000 grams
how many kilograms is 1,216 grams?
<em>Solution:</em>
1000 grams = 1 kilogram
1 gram = 1/1000 kilograms
1216 grams = 1/1000 * 1216 = 1.216 kilograms.
<em> Hence 1216 grams = 1.216 kilograms.</em>
