Determine the balanced chemical equation for this reaction. C8H18(g)+O2(g)→CO2(g)+H2O(g)
ankoles [38]

Answer: balanced reaction equation

C8H18(g) + 25/2 O2(g) ---------> 8CO2(g) + 9H2O(l)

Explanation:

Part A- coefficients

1, 25/2,8,9

Part B

Oxygen is the limiting reactant

Part C

If 1 mole of octane produced 9 moles of water from the balanced reaction equation

0.28 moles of octane will produce 0.28×9= 2.52 moles of water

Part D

If 12.5 moles of oxygen reacts with 1 mole of octane

0.63 moles of oxygen will react with 0.63/12.5=0.0504moles of octane

Amount of octane left= 0.280-0.0504=0.2296 moles

Match the description with either a dehydration reaction or a hydrolysis reaction.
Gelneren [198K]

Answer:

1) Hydrolysis

2)Dehydration

3)Dehydration

4)Hydrolysis

Explanation:

Hydrolysis is the chemical breakdown of substances by water and depends on the chemistry, solubility, pH, and the oxidation–reduction (Eh or redox) potential of compound

<em>https://www.sciencedirect.com/topics/earth-and-planetary-sciences/hydrolysis</em>

With hydrolysis water will be a reactant, not a product, and is associated with breaking down substances. Hence 1 and 4 being a Hydrolysis reaction.

Dehydration on the other hand, is defined as :

In a dehydration reaction, either a hydroxyl group from one molecule combines with a hydrogen atom from the other molecule, or two hydrogen atoms from one molecule combine with an oxygen atom on the other molecule. In either case, water is released, and the two molecules are joined together.

https://www.albert.io/blog/dehydration-synthesis-ap-biology-crash-course/

Therefore it is associated with creating a bond of sorts, and water is a product, which is why 2 and 3 are dehydration.

Hope this helps!
