Answer:
C. The criterion of minimizing chemical waste favors the use of organic solvents.
Explanation:
I chose B on my quiz and got it wrong, then it showed that C was the correct answer. I didn't know this one myself.
The number of liters produced when 126g of glucose is completely reacted with O2 is calculated as follows
find the moles of C6H12O6 used that is moles = mass /molar mass
= 126g /180 g/mol = 0.7 moles
from the equation
C6H12O6 +6O2 = 6CO2 +6 H2O
the reacting ratio of C6H12O6 to Co2 is 1:6 therefore the moles of CO2 = 0.7 x6/1= 4.2 moles
At STP 1 moles of a gas = 22.4 L
what about 4.2 L = how many liters
cross multipication
= (4.2moles x 22 .4 L)/ 1mole = 94.1 L

Answer:
D= 109.5 degrees, 109.5 degrees, 120 degrees
Explanation:
The bond angle observed for any bond between two chemical species depends on the hybridization of the atoms.
However, for organic compounds, single bonds normally involve sp3 hybridized atoms with a bond angle of 109.5 degrees such as in the positions marked a and b.
However, a double bond is made of atoms in sp2 hybridized state with a bond angle of 120 degrees such as in c.
