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%.

I have 345 mL of a 1.5 M NaCl solution. If I boil the water until the volume of the solution is 250 mL, what will the molarity o
likoan [24]
We know that molarity = mol/L, so:

1.5 M = x mol/0.345 L

1.5 M * 0.345 L = x mol => 0.5175 mol

0.5175 mol/0.250 L = 2.07 M

Your new molarity of the solution will be 2.07 M.

ryzh [129]

Answer:

easy

Explanation:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
