Consider the electrochemical constructed using the spontaneous cell reaction, Ni(NO3)2(aq) + Zn(s) = Zn(NO3)2(aq) + Ni(s) The diagram devoid this cell with the two metal electrodes - cathode on the right - and two aqueous solutions. The salt bridge is filled with potassium nitrate.

Which of the following statements are true regarding this electrochemical cell? (You can choose as many)

a) Electrons flow in the wire from anode to cathode
b) The solution on the left is Ni(NO3)2(aq)
c) Nickel ions are reduced at the cathode
d) The cathode is Ni(s)
e) Zinc ions are reduced at the anode
f) The anode is Ni(s)

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.
