Answer: 3.52 grams
Explanation:
Given moles:
moles of oxygen = 6.62
moles of 
According to stoichiometry:
2 moles of benzene reacts with = 15 moles of oxygen
Thus 0.08 moles of benzene will react with = 
moles of oxygen
Thus benzene is the limiting reagent as it limits the formation of products and oxygen is the excess reagent.
As 2 moles of benzene produce = 12 moles of carbon dioxide
0.08 mole of benzene will produce =
of carbon dioxide
Mass of carbon dioxide=
Thus 3.52 g of carbon dioxide are produced.
Sorry, I can't really see the question )-:
Answer:
As they absorb energy, they are broken.
Explanation:
Solutes dissolve when they interact with water. This is because, the attraction of solute particles with each other weakens and become replaced by solute-solvent interaction. As the water surrounds the solute, the solute is now said to be hydrated.
Energy is required to break solute-solute bonds. This energy absorbed in breaking solute-solute bonds is compensated for by the energy liberated when solute particles are hydrated.
If energy required to break solute-solute interaction is less than the energy liberated when solute particles are hydrated, the substance will dissolve in water.
Hence, as a substance dissolve in water, energy is absorbed when solute-solute interactions are broken.
Answer:
<h3>The answer is 1.04 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of coke = 21.36 g
volume = 20.5 mL
So we have
We have the final answer as
<h3>1.04 g/mL</h3>
Hope this helps you
