Hope it helps.
Answer:
The halogens, nitrogen and sulphur are covalently bonded to the organic compounds. In order to detect them, the elements need to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. ... The extract is called sodium fusion extract or Lassaigne's extract.
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96).
Answer:
V = 48.64 L
Explanation:
Given data:
Mass of CO₂ = 85.63 g
Temperature = 273 K
Pressure = 1 atm
Volume of CO₂ = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 85.63 g / 40 g/mol
Number of moles = 2.14 mol
Volume in Litter:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
1 atm× V = 2.14 mol ×0.0821 atm.L/mol.K ×273 K
V = 48.64 atm.L / 1 atm
V = 48.64 L
