Answer: choice C) carbon dioxide.

Explanation: The given diagram is showing the gas coming from the house(kitchen), birds and animals.

In kitchens, the fuel is burned to cook the food and a combustion reaction takes place when the fuel is burned. Combustion of hydrocarbon fuels produces water and carbon dioxide gas.

In respiration process, animals inhale oxygen gas and exhale carbon dioxide gas.

So, the gas A in the diagram must be representing carbon dioxide gas and hence the correct choice is option C) carbon dioxide.

mr_godi [17]

Answer : The value of equilibrium constant (K) is, 424.3

Explanation :  Given,

Concentration of H_2 at equilibrium = 0.067 mol

Concentration of CO at equilibrium = 0.021 mol

Concentration of CH_3OH at equilibrium = 0.040 mol

The given chemical reaction is:

CO+2H_2\rightarrow CH_3OH

The expression for equilibrium constant is:

K_c=\frac{[CH_3OH]}{[CO][H_2]^2}

Now put all the given values in this expression, we get:

K_c=\frac{(0.040)}{(0.021)\times (0.067)^2}

K_c=424.3

Thus, the value of equilibrium constant (K) is, 424.3
