Answer:
Explanation:
Let's call the unknown compound X.
1. Calculate the mass of each element in 1.23383 g of X.
(a) Mass of C
(b) Mass of H
(c)Mass of Fe
(i)In 0.4131g of X
(ii) In 1.2383 g of X
(d)Mass of O
Mass of O = 1.2383 - 0.632 07 - 0.074 157 - 0.195 67 = 0.336 40 g
2. Calculate the moles of each element
3. Calculate the molar ratios
Divide all moles by the smallest number of moles.
4. Round the ratios to the nearest integer
C:H:O:Fe = 15:21:1:6
5. Write the empirical formula
The greatest amount of AB would be produced if the equilibrium constant of the reaction is equal to . Hence, option D is correct.
A number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature.
The equilibrium constant expression is a mathematical relationship that shows how the concentrations of the products vary with the concentration of the reactants.
If the value of K is greater than 1, the products in the reaction are favoured. If the value of K is less than 1, the reactants in the reaction are favoured.
Hence, option D is correct.
