Answer: 3.306 mmol

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

Molarity

n= moles of solute  

V_s = volume of solution in ml

C_2O_4H_2.2H_2O\rightarrow C_2O_4^{2-}+2H^++2H_2O

According to stoichiometry:

1 mole of C_2O_4H_2 gives 2 moles of H^+

1.653 mmol of C_2O_4H_2 gives =\frac{2}{1}\times 1.653=3.306mmo of H^+

Thus number of millimoles of H^+ are 3.306

How does the equilibrium change to counter the removal of A in this reaction? A + B ⇌ AB The equilibrium . Simultaneously, there
kykrilka [37]

Based on Le Chatelier's principle, if the equilibrium of a system is disturbed by changing the temperature, pressure or concentration, then it will shift in a direction to undo the effect of the induced change.

The given equilibrium is:

A + B ↔ AB

Removal of the reactant A implies that the concentration of A has decreased, therefore the equilibrium will shift in a direction to produce more of A. Thus, it will shift to the left and the rate of the reverse or backward reaction will increase.
