Shape of PCl₆⁻¹, is octahedral.
Hybrdisation of PCl₆⁻¹ is sp³d².
This can be seen the image attached.
The angle between phosphorous and chlorine is 90⁰C. As it has octahedral geometry.
So the answer is as follows:
Shape of PCl₆⁻¹, is octahedral.
Hybrdisation of PCl₆⁻¹ is sp³d².
The angle between phosphorous and chlorine is 90⁰C.
Answer:
18.73× 10²³ formula units
Explanation:
Given data:
Number of moles of Ca(NO₃)₂ = 3.11 mol
Number of formula units = ?
Solution:
Avogadro number:
"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance"
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Number of formula units of Ca(NO₃)₂:
1 mole contain 6.022 × 10²³ formula units
3.11 mol × 6.022 × 10²³ formula units / 1 mol
18.73× 10²³ formula units
Answer:
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K
Explanation:
Step 1: Data given
A sample of sulfur hexafluoride gas occupies a volume of 5.10 L
Temperature = 198 °C = 471 K
The volume will be reduced to 2.50 L
Step 2 Calculate the new temperature via Charles' law
V1/T2 = V2/T2
⇒with V1 = the initial volume of sulfur hexafluoride gas = 5.10 L
⇒with T1 = the initial temperature of sulfur hexafluoride gas = 471 K
⇒with V2 = the reduced volume of the gas = 2.50 L
⇒with T2 = the new temperature = TO BE DETERMINED
5.10 L / 471 K = 2.50 L / T2
T2 = 2.50 L / (5.10 L / 471 K)
T2 = 230.9 K = -42.1
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K
