Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂
For every mole of CS₂, 3 moles of Oxygen formed.
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol
Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713 [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g
In short, Your Final Answer would be: 54.21 Grams
Hope this helps!
Answer: C6H6
Explanation: Molecular Formula is the molecular mass divided by the empirical formula mass of CH which is C 12and H is 1 so 12 + 1= 13 g CH
Solution:
78.11 g CH / 13 g CH = 6
The missing data is the value of I.E and E.A for Cl and F, which are, Cl: I.E =1255 kJ/mol, E.A = -348.7 kJ/mol, F: I.E = 1678 kJ/mol, E.A = -327.8 kJ/mol.
Answer:
3.2
Explanation:
The electronegativity is the capacity of an atom to attract an electron in a bond. As higher is it, as higher the electron will be attracted. The ionization energy is the minimum energy necessary to remove one electron of the atom, transforming it on a cation. On the other hand, the electron affinity is the energy that is lost when the atom gains an electron and is transformed on an anion.
Calling the constant as K, and knowing that the electronegative of fluorine (F) is 4.0:
4 = K*(1678 - (-327.8))
2005.8K = 4
K = 2.00x10⁻³ mol/kJ
Thus, for chlorine (Cl):
Electronegativity = 2.00x10⁻³*(1255 - (-348.7))
Electronegativity = 3.2
