What is the percentage of s-character in an sp hybrid? O 25% 50% o 75% O 66%

marishachu [46]

Answer: 50%

Explanation:

The number of electron pairs are 2 for hybridization to be $sp$ and the electronic geometry of the molecule will be linear.

1. percentage of s character in sp hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{2}\times 100=50\%$

2. percentage of s character in $sp^2$ hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{3}\times 100=33.3\%$

3. percentage of s character in $sp^3$ hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{4}\times 100=25\%$

Thus percentage of s-character in an sp hybrid is 50%.

What is the volume of 15.2 grams of SO2 at STP?

kiruha [24]

5.512 litres is the volume of 15.2 grams of sulphur dioxide gas at STP.

Explanation:

Data given:

mass of sulphur dioxide = 15.2 grams

conditions is at STP whech means volume = 22.4 litres

atomic mass of sulphur dioxide = 64.06 grams/mole

Number of moles is calculated as:

number of moles = $\frac{mas}{atomic mass of 1 mole}$

Putting the values in the equation:

number of moles = $\frac{15.2}{64.06}$

= 0.23 moles

Assuming that sulphur dioxide behaves as an ideal gas, we can calculate the volume as:

When 1 mole of sulphur dioxide occupies 22.4 litres at STP

Then 0.23 moles of sulphur dioxide occupies 22.4 x 0.23

= 5.152 litres is the volume.

A scientist is working in a lab and accidentally combines two liquids that quickly form a solution. Which process could be used

PIT_PIT [208]

Answer:

Distillation

Explanation:

The method of distillation can be used to separate the two liquids, if their boiling point is known. The liquid with lower boiling point will be evaporated and its vapours will be captured, while the liquid with higher boiling point will remail in the container in the liquid state.
