Answer:
The answer to your question is Propane
Explanation:
Data
mass of Propane = 3 g
mass of Oxygen = 10 g
limiting reactant = ?
Balanced chemical reaction
C₃H₈ + O₂ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the reactants
C₃H₈ = (12 x 3) + (8 x 1) = 36 + 8 = 44 g
O₂ = 16 x 2 = 32 g
2.- Calculate the theoretical yield C₃H₈ / O₂ = 44/32 = 1.375
3.- Calculate the experimental yield C₃H₈/O₂ = 3/10 = 0.3
4.- Conclusion
The limiting reactant is Propane because the experimental yield was lower than the theoretical yield.
I'm not sure where the question is here. Yes it is true that there is a limited amount of matter on Earth...
Gases have high kinetic energy: the molecules are moving much more than in a liquid or solid. You can cut out A and B. In the liquids, the difference is temperature. If a lower temperature is closer to being solid, and a solid has lower kinetic energy than a liquid, then C is the answer. Hope this helps.
Answer:
The percentage of volume of ethanol is 35%.
<u>Explanation:</u>
The percentage of volume of ethanol is calculated by
Percent of volume of ethanol = (volume of X / total volume) * 100
We are going to assume these volumes will be added together to make 100mL.
Percent volume of Ethanol = (volume of ethanol / total volume) * 100
= 35mL / 100mL * 100
= 35%
