Answer:
E....H+
Explanation:
coz when hydrogen ions are formed they automatically join to form hydrogen
What is the resistance to motion
Answer : The balanced chemical equation will be:
(i) ![2K+H_2SO_4\rightarrow K_2SO_4+H_2](https://tex.z-dn.net/?f=2K%2BH_2SO_4%5Crightarrow%20K_2SO_4%2BH_2)
(ii) ![Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg](https://tex.z-dn.net/?f=Mg%28OH%29_2%2BZn%5Crightarrow%20Zn%28OH%29_2%2BMg)
Explanation :
Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
Part (i):
The balanced chemical equation will be:
![2K+H_2SO_4\rightarrow K_2SO_4+H_2](https://tex.z-dn.net/?f=2K%2BH_2SO_4%5Crightarrow%20K_2SO_4%2BH_2)
This reaction is a single displacement reaction in which most reactive element (potassium) displaces the least reactive element (hydrogen) form their solution.
Part (ii):
The balanced chemical equation will be:
![Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg](https://tex.z-dn.net/?f=Mg%28OH%29_2%2BZn%5Crightarrow%20Zn%28OH%29_2%2BMg)
This reaction is a single displacement reaction in which most reactive element (zinc) displaces the least reactive element (magnesium) form their solution.
Answer:
E) The rate of the reaction is directly proportional to the concentration of the reactant.
Explanation:
Give the characteristic of a first order reaction having only one reactant.
A) The rate of the reaction is not proportional to the concentration of the reactant.
B) The rate of the reaction is proportional to the square of the concentration of the reactant.
C) The rate of the reaction is proportional to the square root of the concentration of the reactant.
D) The rate of the reaction is proportional to the natural logarithm of the concentration of the reactant.
E) The rate of the reaction is directly proportional to the concentration of the reactant.
