2. Write the equation for the equilibrium constant (K) of the reaction 2- 2CrO4 2- (aq) + 2H+ (aq) = Cr₂O7²- (aq) + H₂O(1)

Calculate the reduction potential for a Pt | Cr3+, Cr2+ halfcell in which [Cr3+] is 0.15 M and [Cr2+] is 0.0019 M

what is the Ksp value for silver oxide?

I need help calculating the following.

Please attend both the questions there are subparts thank you so much

WHAT IS THE USE OF SULFURIC ACID IN DETERMINATION OF IRON IN DIET SUPPLEMENT TABLETS?

Using data from the Standard Reduction Potentials table, place the following in order of increasing strength as oxidizing agents (all under standard conditions). (Use the appropriate symbol to separate substances in the list.) Cr³+, Ba²+, Au³+, Cu²+, K+, and Cd²+ Help chemPad XX → Greek

Enter electrons as e". Use smallest possible integer coefficients. If a box is not needed, leave it blank. Use the table 'Standard Reduction Potentials' located in the 'Tables', to predict if a reaction will occur when Mg metal is put into a 1M aqueous Cu2+ solution. If a reaction will occur, write a balanced net ionic equation for the reaction. If no reaction will occur, leave all boxes blank.
