Answer:
The correct statements are A amine groups are fully protonated and can be described with the chemical formula NH3+ B carboxylic acid functional groups are de protonated and can be be described with the chemical formula COO- C Amine functional groups are positively.
Explanation:
If we study the biochemical structure of an amino acid we wil see that an amino group or -NH2 is present at one end and a carboxylic group or COOH is present at another end.
Now the fact the that when an amino acid exist as zwitterion it contain same number of positive charge as well as same number of negative charge.So during zwitterion formation the carboxylic acid or -COOH liberates a proton and exist as COO- whereas the amine group accepts that proton and exist as NH3+.
Beside this the amine group -NH2 after the formation of zwitterion gains a positive charge and exist as -NH3+.
Answer:
a. 0.171M
b. 0.0938M
c. 0.284
d. 1.99atm
e. 1.88
Explanation:
Hello,
In this case, for the given reaction whose balance should be corrected as:
For which the law of mass action, in terms of the change due to stoichiometry and the reaction extent, turns out:
Thus, the initial concentration of hydrogen sulfide is:
Now, since the equilibrium amount of sulfur is given, the change due to equilibrium reaching is:
Therefore:
a. Equilibrium concentration of hydrogen:
b. Equilibrium concentration of hydrogen sulfide:
c.) Equilibrium constant, Kc:
d.) Partial pressure of sulfur gas:
e. Kc, for the reaction:
In that case, it equals the inverse halved initial reaction, whose modification is related as:
Best regards.
Answer:
Frequency
Explanation:
It’s kinda self-explanatory but bascially speed=wavelength times frequency
Acetylene appear as gas and is unstable and thus kept in presence of other solution such as liquid ammonia.
Ethanol on reacting with ammonia produces ethylamine as follows:
Ethanol again on reacting with ethylamine produces diethylamine and triethylamine as follows:
