Answer:
Explanation:
The oxidation state of S is (-2) and that of Mg is (+2) since Mg loses two electrons to S
<u>Answer: </u>The equation which is wrong is
<u>Explanation:</u>
For the given reaction:
The expression for is given by:
The concentration of solids are taken to be 1, only concentration of gases and liquid states are taken. The pressure of only gases are taken.
Relationship between is given by the expression:
where,
= number of moles of gaseous products - number of moles of gaseous reactants
R = gas constant
T= temperature
For the above reaction,
= number of moles of gaseous products - number of moles of gaseous reactants = 0 - 3 = -3
Hence, the expression for is:
Therefore, the equation which is wrong is
I assume you’re looking for a balanced equation.
SiCl4 + 2H2O = SiO2 + 4HCl
Given equation:
P + O2 → P2O5
In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product
Reactants Products
P = 1 P = 2
O = 2 O = 5
The balanced equation would be:
4P + 5O2 → 2P2O5
Reactants Products
P = 4 P = 4
O = 10 O = 10
Ans: D)
Answer:
Explanation:
Write the balance chemical equation ,
initial concenration of
lets assume that degree of dissociation=
concenration of each component at equilibrium:
as is very small then we can neglect
therefore ,
Eqilibrium concenration of
