Answer:
74.566
Explanation:
C6H6 + 02 =6CO2 + 3H2O
2C6H6 + 15O2=12CO2 + 6H2O
mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol
mass conc = 2x78=156
mm CO2= 12+(16x2)=
12+32= 44gram/mol
mass conc of CO2 = 12x44
= 528
from The equation
156g of C6H6=528g of CO2
22.031g of C6H6=Xg of CO2
therefore, Xg=
22.031 x 528/ 156
= 74.566g
Answer:
D. An endangered species is in danger of becoming extinct in the near future. A threatened species could become endangered in the near future.
Explanation:
Answer:
A. a mixture.
Step-by-step explanation:
If the perfume is made from water and anything else, it is a mixture.
B. is <em>wrong</em>, because water is a liquid at room temperature.
C. is <em>wrong</em>, because water is a compound.
D. is <em>wrong</em>, because the perfume is a mixture of water and other compounds.
Nitrogen dioxide is one of the primary components of air pollution. It is released by the combustion of nitrogen oxide.
<h3 /><h3>How do you calculate the percentage yield of nitrogen oxide?</h3>
Given:
- Mass of nitrogen oxide consumed = 1500 kg
- Mass of nitrogen oxide produced = 1500 kg
The given chemical equation of nitrogen oxide is:
Now, to calculate the percentage yield, the following conversion factor should be used:
Nitrogen dioxide = 2300 kg
The percentage yield will be:
Percentage yield = 65.2 %
Thus, the percentage yield of nitrogen dioxide is 65.2%.
