Answer:
Explanation:
We are given that
Distance between two tiny particles=d=1mm=
Force,F=5 N
We have to find the magnitude of the charge on each of these particles.
Let charge on each particle=q
By Coulomb's law of force
Where
Substitute the values
Aluminium reacts with sulphuric acid

Answer:
A. MeONa
Explanation:
One of the methods to prepare alkenes are eliminations.
The E2 reaction (for elimination, bimolecular) occurs when an alkyl halide is treated with a strong base, such as hydroxide ion or alkoxide ion (RO⁻).
It is the most common mechanism that occurs for an elimination.
The methoxide ion is a strong base that will attack the neighboring hydrogen of the halide ion and will start removing H⁺ at the same time that the double bond of the alkene begins to form and the group X begins to leave.
Then, the neutral alkene is produced when the C – H link and X group has left with the electron pair of the bond C – X (mechanism in attachment).
Therefore, MeONa would be an appropiate reagent.
Answer:
Explanation:
1. the 1/2 reaction that occurs at the cathode
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
2 the 1/2 reaction that occurs at the anode
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
E0 = -0.59v
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
E0 = 1.39v
3Cl2 (g) + 2MnO2 (s) + 8OH^(−) (aq)---------> 6Cl^(−) (aq) + 2MnO4^(−) (aq) + 4H2O (l)
E0cell = 0.80v
Answer:
Crude Oil
Explanation:
Crude oils is when the oil has not been cleaned nor added any chemicals.
