Explanation:
The initial concentrations for a mixture :
Acetic acid at equilibrium = 0.15 M
Ethanol at equilibrium = 0.15 M
Ethyl acetate at equilibrium = 0.40 M
Water at equilibrium = 0.40 M
Initially:
0.15 M 0.15 M 0.40 M 0.40 M
At equilibrium
(0.15-x)M (0.15-x) M (0.40+x) M (0.40+x) M
The equilibrium constant is given by expression
![K_c=\frac{[CH_3CO_2C_2H_5][H_2O]}{[CH_3COOH][C_2H_5OH]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCH_3CO_2C_2H_5%5D%5BH_2O%5D%7D%7B%5BCH_3COOH%5D%5BC_2H_5OH%5D%7D)
Solving for x:
x = 0.0333
The equilibrium concentrations for a mixture :
Acetic acid at equilibrium = (0.15-x)M = (0.15-0.033) M = 0.117 M
Ethanol at equilibrium = (0.15-x)M = (0.15-0.033) M = 0.117 M
Ethyl acetate at equilibrium = (0.40+x)M = (0.40+0.033) M = 0.433 M
Water at equilibrium = (0.40+x)M = (0.40+0.033) M = 0.433 M
Answer:
Amides are suitable to synthesize aniline
Explanation:
Amide are basically used to synthesize aniline.
The chemical formula of Aniline is C6H5NH2 while that of Amide is RCONH2
Amide are solids that can be easily converted to amines.
Newton’s 2nd law? Maybe I’m not completely sure
Answer:
It would have a charge of +2.
Explanation:
A proton has a charge of +1, an elctron has a charge of -1, and a neutron has a charge of 0. Ignore the neurons since they have a charge of 0. Since there are 20 protons and 18 electrons (20-18), the overall charge of the atom is +2.
Cadium
Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period.
