Atoms have a tendency to complete their outer energy level. This is known as octet rule. That is because octet refers to 8 valence electrons, making a element stable in its outer shell.

Answer : Option C) The Octet Rule

Explanation : Atoms have a tendency to complete their outer energy level. This is known as Octet Rule.

The octet rule is a chemical rule of thumb which reflects the observation, that atoms of main-group elements tends to combine in such a way that each atom gets eight electrons in its valence shell, which gives it the same electron configuration as that of a noble gas.

In short, the tendency of an atom to fill its valence shell and attain a stable state it acquires or donates the electron is called as octet rule.

A student titrated 20 ml of 0.410 m hcl with 0.320 m naoh. determine the volume of naoh needed at equivalence point
Aleksandr-060686 [28]

Answer:

25.6mL NaOH

Explanation:

We are given the Molarity of the solution (\frac{moles}{liters}) and the volume of the solution (.02L).

By multiplying the two together, we can find the moles of solution that are reacted with HCl.

moles = \frac{.410 moles}{L} *.02L

This gives us .0082 moles of HCl.

We then find the moles of NaOH that are needed to react with the HCl using the equation.

HCl + NaOH = NaCl + H_{2} O

As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.

Dividing this value by the Molarity of the solution

\frac{.0082mol}{.320mol/L}

Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
