A molecule in which the central atom has no lone pairs and forms four single bonds is said to have a ________ shape.
2 answers:
Answer: tetrahedral
Explanation:
Hybridization is calculated using the Lewis dot structures of all the compounds.
Formula used to calculate the number of atomic orbitals around central metal atom is:
Number of atomic orbitals around central metal atom = Number of bond pairs + Number of lone pairs
Bond pairs for a double bond and triple bond is taken as 1 only.
Given: Number of bond pairs = 4
Number of lone pairs = 0
If Number of atomic orbitals around central metal atom are 4 , the hybridization is and electron domain geometry is tetrahedral.

Answer:
91.7°C
Explanation:
We suppose you have a formula to work from. However, that is not supplied with this problem statement, so we looked one up.
The formula in the attachment is supposed to have good accuracy in the temperature range of interest. It gives vapor pressure of water in kPa, not mmHg, so we needed the conversion for that, too.
560 mmHg corresponds to about 74.66 kPa. The attached "Buck equation" formula is used to find the corresponding temperature. The exponential equation could be solved algebraically using logarithms and the quadratic formula, but we choose to find the solution graphically.
Water boils at about 91.7 °C on Mt. Whitney.
Answer:
The final pressure of the gas is:- 21.3 kPa
Explanation:
Using Boyle's law
Given ,
V₁ = 10.0 L
V₂ = 45.0 L
P₁ = 96.0 kPa
P₂ = ?
Using above equation as:
The final pressure of the gas is:- 21.3 kPa
