Answer: A physical change is a change that can be undone.
Explanation: An example of this is mixing red blocks, green blocks, and blue blocks. You can easily separate them.
Tetracarbon dioxide is an oxide of carbon, a chemical compound of carbon and oxygen, with chemical formula C4O2 or O=C=C=C=C=O. It can be regarded as butatriene dione, the double ketone of butatriene . Chemical formula
C4O2
Molar mass
80.042
Answer:
Equilibrium constant for is 0.5
Equilibrium constant for decomposition of is
Explanation:
dissociates as follows:
initial 0.72 mol 0 0
at eq. 0.72 - 0.40 0.40 0.40
Expression for the equilibrium constant is as follows:
Substitute the values in the above formula to calculate equilibrium constant as follows:
Therefore, equilibrium constant for is 0.5
Now calculate the equilibrium constant for decomposition of
It is given that is decomposed.
decomposes as follows:
initial 1.0 M 0 0
at eq. concentration of is:
Expression for equilibrium constant is as follows:
Substitute the values in the above expression
Equilibrium constant for decomposition of is
