Answer:
Explanation:
Double displacement reaction: it is a chemical reaction in which the reactants exchanges their ions to form new compounds as a products.
All the reaction are example of double displacement reaction beside reaction where magnesium iodide is reacting with manganese(II) sulfate to give magnesium sulfate and manganese(IV) iodide .
In this reaction , charge on manganese have changed from 2+ to 4+. Manganese in getting oxidized. Example of an oxidation reaction. Hence, this reaction is not an example of double displacement reaction.
Answer:
- The NaCl solution will have higher boiling point.
Explanation:
- C2H6O2 is a molecular substance. Meaning that when it dissolves it will remain this way:
C2H6O2 ---------> C6H12O6 (aq)
- Sodiumchloride (NaCl) is an ionic substance. Meaning that when it dissolves, it will create ions:
NaCl(s)-------> Na+(aq) + Cl- (aq)
Conclusion:
- NaCl is an ionic compound and C2H6O2 is a molecular compound. Ionic compounds have higher boiling points than molecular compounds. Therefore, NaCl will have the higher boiling point.
I would say a strong base. NaOH is like chlorox
Answer:
Light waves are the fastest in existince.
