Answer: The chemical formula for the formula given in the image is .
Explanation: There are many ways in which a model can be represented:
- Molecular Formula
- Ball and Stick formula
- Expanded Formula
- Condensed Formula
- Skeletal Formula
This molecule is represented by the Expanded Structural Formula and by seeing in the image we can count the number of each element present.
Number of Carbon atoms present = 4
Number of Hydrogen atom present = 9
Number of Oxygen atom present = 2
Correct representation for this will be .

Answer:
Value of equilibrium constant is 0.0888
Explanation:
Both and
are gaseous. Hence equilibrium constant depends upon partial pressures of
and
.
Initially no and
were present.
Hence mole fraction of and
at equilibrium can be calculated from coefficient of
and
in balanced equation.
Mole fraction of = (number of moles of
)/(total number of moles of
and
) =
Mole fraction of = (number of moles of
)/(total number of moles of
and
) =
Let's assume both and
behaves ideally.
Therefore partial pressure of ,
and P_{CO_{2}}= x_{CO_{2}}.P_{total}
Where x represents mole fraction
So,
So,
