Kc is 1.67 x 10^20 at 25 °C for the formation of iron(III) oxalate complex ion: Fe^3+ (aq) + 3C2O4^2- (aq) <--> [Fe(C204)3]^3- (aq)

Determine the number of moles of C2O4^2- used to react with 0.53 moles of Fe^3+.

Explanation:

Hello there!

In this case, according to the given information and chemical equation, it turns out possible for us to calculate the moles of C2O4^2- by firstly setting up the equilibrium expression:

However, according to the question, we just need to apply the given 1:3 mole ratio in the chemical reaction, of iron (III) ions to oxalate ions to obtain:

Regards!

they both have a y in them

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
