Answer: carbon-containing compounds with covalent bonds
Explanation:
The term "organic compound" refers to the group of carbon-containing compounds such as glucose (C6H12O6), Propane (C3H8), ethyne (C2H2) etc, where the carbon atoms in them are covalently bounded to other atoms such as hydrogen, oxygen, phosphorus, nitrogen etc
Examples of organic compounds are ethanol (C2H5OH), ethylamine (C2H5NH2) etc.
Thus, organic compound are carbon-containing compounds with covalent bonds to other atoms.
Answer: 2,3 * 4 = 9,2
Explanation:
If 1 mole CH4 has 4 H atoms 2,3 moles of CH4 will have 9,2 H atoms.

Answer:
Explanation:
Hello there!
In this case, according to the Henderson-Hasselbach equation, it is possible to write:
![pH=pKa+log(\frac{[A^-]}{[HA]} )](https://tex.z-dn.net/?f=pH%3DpKa%2Blog%28%5Cfrac%7B%5BA%5E-%5D%7D%7B%5BHA%5D%7D%20%29)
Next, since we are given the pH and the [A–]/[HA] ratio, we can solve for the pKa as shown below:
![pKa=pH-log(\frac{[A^-]}{[HA]} )](https://tex.z-dn.net/?f=pKa%3DpH-log%28%5Cfrac%7B%5BA%5E-%5D%7D%7B%5BHA%5D%7D%20%29)
Now, we plug in the values to obtain:
Next, Ka is:
Best regards!
