Answer:
D. Element
Explanation:
Fe is an element. It isn't more than one element chemically combined (compound), it isn't a charged particle (ion), and it isn't the smallest possible unit of multiple atoms combined together (molecule).
Answer : The number of moles of
gas added must be, 1.59 moles.
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
The given equilibrium reaction is,

Initial conc. 2.86 x 0 0
At eqm. (2.86-1.30) (x-1.30) 1.30 1.30
The expression of
will be,
![K_{eq}=\frac{[SO_3][NO]}{[SO_2]NO_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BSO_3%5D%5BNO%5D%7D%7B%5BSO_2%5DNO_2%5D%7D)
Now put all the given values in this expression, we get:


Thus, the number of moles of
gas added must be, 1.59 moles.
