sp2 Hybridization. The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.

<h3>How do you describe hybrid orbitals?</h3>

A hybrid orbital is an orbital formed by the combination of two or more atomic orbitals. The resulting orbital has a different shape and energy than the component orbitals that form it. Hybridization is used to model molecular geometry and to explain atomic bonding.

<h3>What is the hybridization of the s atom?</h3>

The middle S atom containing the 5 valence atomic orbitals is basically hybridized to form five sp3d hybrid orbitals. In 2P-orbitals, four hybrid orbitals are overlapped and the fifth one contains a lone pair.

A balloon has a volume of 10,500 liters, and the temperature is 15°C. If the temperature were -25°C, what would the volume of th

harina [27]

Answer is: b) 9,042 L.
Ideal gas law: p·V = n·R·T.
p is the pressure of the gas.
V is the volume of the gas.
n is amount of substance.
R is universal gas constant.
T is temperature.
T₁ = 15°C = 288 K.
V₁ = 10,5 L.
T₂ = -25°C = 248 K.
V₂ = ?
V₁/T₁ = V₂/T₂
V₂ = 10,5 L · 248 K ÷ 288 K
V₂ = 9,042 L.

Assume that the NO, concentration in a house with a gas stove is 150 pg/m°. Calculate the equivalent concentration in ppm at STP

jok3333 [9.3K]

Explanation:

It is known that for $NO_{2}$ , ppm present in 1 $mg/m^{3}$ are as follows.

1 $\frac{mg}{m^{3}}$ = 0.494 ppm

So, 150 $pg/m^{3}$ = $\frac{150}{1000} mg/m^{3}$

= 0.15 $mg/m^{3}$

Therefore, calculate the equivalent concentration in ppm as follows.

$0.15 \times 0.494 ppm$

= 0.074 ppm

Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.

Law of Universal Gravitation (what factors affect gravity and how?)

olya-2409 [2.1K]

Explanation:

Hey there!

According to the law of gravitation, the factors that affects the gravity are:

Mass of the heavenly bodies.
Distance from the centre of the body to next body.

Mass of heavenly bodies:The mass of heavenly bodies affect the gravity. We know that gravity is directly proportional to the mass of heavenly bodies. so, when the mass is more there is more gravity and where there is less mass there is less gravity.

Distance from the centre of the body to next body: It is one of the factor to influence gravity. When there is more distance there is less gravity and where there is distance more force is there. Is means gravity is inversely proportional to the distance between the bodies.

Hope it helps...

The electronic configuration of an element is given below.

drek231 [11]

Answer:

C. It is reactive because it must gain two electrons to have a full outermost energy level.

Step-by-step explanation:

The electron configuration of this element ends in 2s²2p⁴.

A filled energy level would end in 2s²2p⁶.

The element will be reactive, because it must gain electrons to have a full energy level, and it needs two more electrons to do this.
