Chemistry
1 answer:
DaniilM [7]3 years ago
6 0

Answer:

Pressure is 2.32 atm

Explanation:

Pressure . Volume = moles . Constant Ideal Gases . Temperature (K)

Pressure = (moles . Constant Ideal Gases . T° K) / Volume

T°K = T°C + 273 → 61°C + 273 = 334 K

Let's replace every data:

P = (0.214 mol . 0.082 L.atm/mol.K . 334K) / 2.53L

P = 2.32 atm

rewona [7]

Hey there!

No of hybrid orbitals , H = ( V +S - C + A ) / 2

Where H = no . of hybrid orbitals

V = Valence of the central atom = 5

S = No . of single valency atoms = 4

C = No . of cations = 1

A = No . of anions = 0

For PCl4 +

Plug the values we get H = ( 5+4-1+0) / 2

H =  4 ---> sp3 hybridization

sp3 hybrid orbitals are used by phosphorous in the PCl4+ cations

Answer C

Hope that helps!

The mass number for an atom is numerically equal to which quantity
Misha Larkins [42]

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

Explanation:

protons

The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
