Give the number and type of hybrid orbital that forms when each set of atomic orbitals mixes:
evablogger [386]

<u>Two hybrid </u>orbitals of <u>sp </u>type forms when each set of atomic orbitals mixes one p and one s

<h3>What is orbital hybridization?</h3>

In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.

For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.

Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

Match each weather phenomena listed below to its appropriate scale of motion. longwave ridges and troughs microscale a high pres
Ipatiy [6.2K]

Answer:

Longwave ridges = Global scale

High pressure system persists over the central plains for 4 days = Synoptic scale

Supercell thunderstorm that lasts for over an hour = mesoscale

A turbulent eddy = microscale

Explanation:

Global scale has a range of the entire earth

synoptic scale has a range of about 100-1000km and can last fro days to weeks

mesoscale has a range of 4-100km and lasts for a day maximum

microscale is the least of all atmospheric motions.

HELPPP!!! What is the volume of a 1.31 moles sample of gas if the pressure is 904 mmHg and the temperature is 37. degrees Celsiu
Tju [1.3M]

Answer:

27.99 dm³

Explanation:

Applying

PV = nRT................ Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

From the question, we were aksed to find V.

Therefore we make V the subject of the equation

V = nRT/P................ Equation 2

Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

V = (1.31×310×0.082)/(1.1897)

V = 27.99 dm³

Some gas molecules move at speeds of 542 meters per second. How fast is this in miles per hour? 542 =? 1h Solve by dimensional a
artcher [175]

Answer:

1212.42\ \text{mph}

Explanation:

We need to convert 542\ \text{m/s} to \text{miles/hour}

1\ \text{mile}=5280\ \text{ft}

1\ \text{ft}=12\ \text{inches}

5280\ \text{ft}=5280\times 12=63360\ \text{inches}

1\ \text{inch}=2.54\ \text{cm}=0.0254\ \text{m}

63360\ \text{inches}=63360\times 0.0254=1609.344\ \text{m}

So

1\ \text{mile}=1609.344\ \text{m}\\\Rightarrow 1\ \text{m}=\dfrac{1}{1609.34}\ \text{miles}

1\ \text{hour}=60\times 60\ \text{seconds}\\\Rightarrow 1\ \text{s}=\dfrac{1}{3600}\ \text{hour}

542\ \text{m/s}=\dfrac{\dfrac{542}{1609.34}}{\dfrac{1}{3600}}=1212.42\ \text{mph}

The speed of the gas molecules is 1212.42\ \text{mph}.
