Answer:
Answer for the question:
You replicate the CEC analysis of a secondary alcohol you performed in the lab using a reverse phase TLC plate producing the TLC plate below. Based on this TLC plate and the mnemonic in your notes, what can you conclude about the stereochemistry of the alcohol? (1 pts)
is given below which explains the best option for the answer.
Explanation:
The enantiomer of the alcohol cannot be determined.
Answer:
3.05 ×10³ Kg/m³
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Density = 3.05 g/cm³
Density in Kg/m³ = ?
Solution:
In order to convert the g/cm³ to Kg/m³ we will multiply the value with 1000.
3.05 g/cm³ × 1000 Kg/m³ / 1 g/cm³
3050 Kg/m³
In scientific notation:
3.05 ×10³ Kg/m³
Answer:
0.0018 mol/min is the average rate of carbon dioxide gas production in moles per minute during the 10 minutes.
Explanation:
Pressure of carbon dioxide gas = P = 0.25 atm
Volume of carbon dioxide gas = V = 5.0 L
Moles of carbon dioxide gas = n
Temperature of the carbon dioxide gas,T = 550°C = 550+273 K = 823 K
Using an ideal gas equation :
n = 0.018 mol
In 10 minutes pressure of carbon dioxide gas reached to 0.25 atm
Average rate of production of moles of carbon dioxide gas per minute in duration of 10 minutes:
0.0018 mol/min is the average rate of carbon dioxide gas production in moles per minute during the 10 minutes.
