Answer: the model in a mixture would not be precise because you are mixing two or more ingredients in with each other that makes it homogelis or something sorry i forgot the word.
Explanation:
Answer:
Percent yield of CO₂ is 6.25 %.
Explanation:
Given data:
Percent yield of CO₂ = ?
Actual yield of CO₂ = 28.16 g
Number of moles of C₈H₁₈ = 8.000 mol
Number of moles of O₂ = 16.00 mol
Solution:
Chemical equation:
2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
Now we will compare the moles of C₈H₁₈ and O₂ with CO₂.
C₈H₁₈ : CO₂
2 : 16
8.000 : 16/2×8.000 = 64 mol
O₂ : CO₂
25 : 16
16 : 16/25×16= 10.24 mol
Less number of moles of CO₂ are produced from 16 moles of O₂. it will limit the yield of CO₂.
Grams of CO₂ produced:
Mass = number of moles × molar mass
Mass = 10.24 mol × 44 g/mol
Mass = 450.56 g
Percentage yield of CO₂:
Percentage yield = actual yield / theoretical yield × 100
Percentage yield = 28.16 g/ 450.56 g× 100
Percentage yield = 6.25 %
The ice<span> cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the </span>ice<span> particles gather heat energy from the warmer air. Therefore the </span>ice<span> particles have enough energy to break apart (</span>melt<span>)into smaller particle arrangements.</span>
<span>Compared to a weak acid, a strong acid has a greater habit of losing it's proton (hydrogen). For example, when hydrochloric acid (strong) encounters water, it is much more likely to donate its hydrogen to water, compared to nitrous acid (weak).</span>
