The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
Simply, the reactants are the original substances that are present at the beginning of a reaction. For example, in this reaction: 2Na + Cl2--> 2NaCl, the reactants are the Na and Cl.
NaCl itself is not a change. If you mean the formation of it from sodium ad chlorine, however, it is a chemical change.
Balanced equation for Sodium and Chlorine is: 2Na + Cl2 --> 2NaCl
The formation of water form hydrogen and oxygen: 2H2 + O2 --> 2H2O The formation of sodium chloride from sodium and chlorine: 2Na + Cl2 --> 2NaCl
2NaCl + H2SO4 = Na2SO4 + 2HCl
The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
Double-Replacement-Apex
Type your answer here... 2Na (s) + Cl2 (g) → 2NaCl (s)
The synthesis reaction is: 2Na + Cl2 --> 2NaCl. The decomposition reaction is: 2NaCl --> 2Na + Cl2.
Combination Reaction
It is a double replacement reaction, also called a double displacement reaction.
No, Na2S(aq) + 2HCl(aq) ®2NaCl(aq) + H2S(g) is a double displacement reaction.
Single replacement A+
2Na+C12 -> 2NaCl
2NaCl+(NH4)2CO3
This is not a chemical reaction.
