The required orbital velocity is a little more than 17,000 mph (about 27,400 kph).
Answer:
Option A:
Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)
Explanation:
The half reactions given are:
Zn(s) → Zn^(2+)(aq) + 2e^(-)
Cu^(2+) (aq) + 2e^(-) → Cu(s)
From the given half reactions, we can see that in the first one, Zn undergoes oxidation to produce Zn^(2+).
While in the second half reaction, Cu^(2+) is reduced to Cu.
Thus, for the overall reaction, we will add both half reactions to get;
Zn(s) + Cu^(2+) (aq) + 2e^(-) → Cu(s) + Zn^(2+)(aq) + 2e^(-)
2e^(-) will cancel out to give us;
Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)
Answer:
The answer to your question is Synthesis and Endothermic
Explanation:
Balanced chemical reaction
H₂ + F₂ ⇒ 2HF + 546 kJ
Chemical reactions can be classified in different ways, so I suggest two names of this reaction.
1.- This is a synthesis reaction because two different reactants form a new compound.
2.- This is an endothermic reaction because it was needed to supply 546 kJ of energy so that the reaction proceeds.
