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
<h2>Answer:</h2>
Option B is correct.
b. extending outward is more economical than extending upward
<h2>Explanation:</h2>
people tend to move from rural areas to urban for the greater facilities that they can enjoy at cities. This urban sprawl is also very economic because people will get more chances of jobs, business and work hence improving the economy.
Answer:Climate is defined as the average state of everyday's weather condition over a period of 30 years.[1][2] It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
Explanation:
Answer:
the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
