Answer:
The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. However, the variable x will represent the concentration of the hydroxide ion. The pH is found by taking the negative logarithm to get the pOH, followed by subtracting from 14 to get the pH.
Explanation:
Answer: ![NH_3](https://tex.z-dn.net/?f=NH_3)
Explanation:
a)
: This is a non polar covalent compound which are held by weak vanderwaal forces of attraction.
b)
: This is a covalent compound which is polar due to the presence of lone pair of electrons and are held by dipole-dipole forces of attraction.
c)
: These are joined by a special type of dipole dipole attraction called as hydrogen bond. It forms between electronegative nitrogen atom and hydrogen atom and is the strongest interaction.
d)
: This is a covalent compound and is non polar which are held by weak vanderwaal forces of attraction.
e)
: This is a covalent compound and is non polar which are held by weak vander waal forces of attraction.

Answer:
B. Na
Explanation:
To identify an atom, you simply need to look at the number of protons. This atom has 11 protons. On the periodic table, you can see that the element with 11 protons is sodium (Na).
