Answer: Two equatorial positions so as to minimize the repulsion.
Explanation:
Formula used for calculating number of electrons :
[tex]\frac{1}{2}[V+N-C+A][/tex]
where,
V = number of valence electrons present in central atom = 8
N = number of monovalent atoms bonded to central atom = 4
C = charge of cation = 0
A = charge of anion = 0
Now we have to determine the hybridization of the [tex]XeF_4[/tex] molecule.
[tex]\frac{1}{2}[8+4-0+0]=6[/tex]
Bond pair electrons = 4
Lone pair electrons = 2
The number of electrons are 6 that means the hybridization will be [tex]sp^3d^2[/tex] and the electronic geometry of the molecule will be octahedral.
The molecular geometry will be square planar as two alternate positio ns will be occupied by lone pair of electrons so as to minimize the repulsion.

This picture represents a model of:
Question 5 options:
Oxygen
Calcium
Boron
Neon
Answers
Answer:
The picture represents oxygen.
Explanation:
There are two notable ways you can figure this out:
1) Since there are eight protons, you can automatically know that you are looking for an element with an atomic number of 8. This is because the atomic number is the number of protons in an atom.
2) You can also note the number of electrons on the outer shell. These are called valence electrons. You can then see that the element has 6 valence electrons. Beginning with Lithium on the periodic table and count by ones going from left to right in period 2 of the periodic table until you get to 6. What element is that? It is indeed oxygen.
Answer:
Oxygen
Explanation:
Neons contain 8 protons and 10 ELECTRONS
Boron contains 5 protons an 5 electrons
calcium contains 20 electrons an 0 protons

Which of thes statements about heating up land and water is true
Answers
Answer:
b its radiant energy that heats up the earth.
Explanation:
Answer:
The answer is D
Explanation:
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy.
Using the van der waals equation, the pressure in a 22.4 L vessel containing 1.50 mol of chlorine gas at 0.00 c is____________atm. (a= 6.49L^2-atm/mol^2, b=0.0562 L/mol)
A. 1.50
b. 0.676
c. 0.993
d. 1.48
e. 1.91
Answers
Answer:
D. 1.48atm
Explanation:
Van der waals equation is given as:
(P +an²/v²) (v - nb) = nRT
Where;
P = pressure (atm)
V = volume (L)
R = gas constant (0.0821 Latm/molK)
a and b = gas constant specific to each gas
T = temperature (K)
n = number of moles
According to the given information; V = 22.4L, T = 0.00°C (273.15K), R = 0.0821 Latm/molK, a = 6.49L^2-atm/mol^2, b = 0.0562 L/mol, n = 1.5mol
Hence;
(P + 6.49 × 1.5²/22.4²) (22.4 - 1.5×0.0562) = 1.5 × 0.0821 × 273.15
(P + 6.49 × 2.25/501.76) (22.4 - 0.0843) = 33.638
(P + 0.0291) (22.316) = 33.638
22.316P + 0.649 = 33.638
22.316P = 33.638 - 0.649
22.316P = 32.989
P = 32.989/22.316
P = 1.478
P = 1.48atm

An object on top of a building has a GPE of 23,048j and a mass of 39kg, What is the height of the object
Answers
Answer:
59.1 mExplanation:
The height of the object can be found by using the formula
[tex]h = \frac{p}{mg } \\ [/tex]
where
p is the potential energy
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
[tex]h = \frac{23048}{39 \times 10} = \frac{23048}{390} \\ = 59.0974...[/tex]
We have the final answer as
59.1 mHope this helps you
