Answer:
D) 3Ni (s) + 2Fe(NO3)3 (aq) → 3Ni(NO3)2 (aq) + 2Fe (s)
Explanation:
According to the metal activity series, only a metal higher in the reactivity series will replace another. A metal can only displace metal ions listed below it in the activity series, but not above.
Iron is higher in the activity series than nickel so it will displace nickel.
The balanced chemical equation will be as follows:
3Ni (s) + 2Fe(NO₃)₃ (aq) → 3Ni(NO₃)₂ (aq) + 2Fe (s)
Hope that helps.
There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:
Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.
It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.
Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.
To know more about Lewis structure.

Answer: H2O
Explanation: The given balanced chemical reaction is,
This reaction is a reversible reaction.
The rate of forward reaction will be,
The rate of backward reaction will be,
And at equilibrium the rate of reaction is equal to the rate of backward reaction divided by the rate of forward reaction.
Answer:
Iodine. The reaction between hot iron and iodine vapor produces gray iron(II) iodide, and is much less vigorous. This reaction, the equation for which is given below, is difficult to carry out because he product is always contaminated with iodine. Iodine is only capable of oxidizing iron to the +2 oxidation state.
