This is an incomplete question, here is a complete question.
The reaction below has a Kp value of 3.3 × 10⁻⁵. What is the value of Kc for this reaction at 700 K?
Answer : The value of is,
Explanation :
The relation between and is:
where,
= equilibrium constant at constant pressure =
R = gas constant = 0.0821 L.atm/mol.K
T = temperature = 700 K
= change in number of gaseous moles = Product moles - Reactant moles = (2+1) - (2) = 3 - 1 = 1 mol
= equilibrium constant
Now put all the given values in the above expression, we get:
Therefore, the value of is,
Moles XeF6 = 10.0 g/ 245.28 g/mol=0.0408
the ratio between F2 and XeF6 is 3 : 1
moles F2 required = 3 x 0.0408=0.122
mass F2 = 0.122 mol x 37.9968 g/mol=4.64 g
Answer:
personally I think it's a but it could also be D.
But yeah personally I would say A
Answer:
Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent or non ionic bonds.
<u>IONIC COMPOUDS</u>
- Iron and chlorine (FeCl2) , ( FeCl3)
- Chlorine and Lithium (LiCl)
- oxygen and calcium ( CaO)
- Potassium and Sulphur ( K2S)
<u>NON IONIC COMPOUNDS</u>
- Potassium and Calcium (covalent bond)
- Sulphur and Bromine (covalent bond)
