Answer:
A. Solution, Colloid, Suspension
Hope i could help
C6H12O6 + O2 = CO2 + H2O
Balanced Equation:
1 = C6H12O6
6 = O2
6 = CO2
6 = H2O
The law of conservation of mass states that mass can neither be created or destroyed in a chemical reaction.
Standard reduction potential of Cd2+ = -0.403 v
Standard reduction potential of Cr3+ = -0.74 v
Here, reduction potential of Cd2+ is higher as compared to Cr3+. Hence, it will preferentially undergo reduction.
The electrochemical cell is represented as
Cr/Cr3+// Cd2+/Cd
Now, standard EMF of cell = E = ECd2+/Cd - ECr3+/Cr
= - 0.403. - (-0.74)
= 0.337 v
