c is the answer i odnt know the rest im only a sophmore
Good the equation is balanced already
Answer:
14
Explanation:
Silicon has atomic number 14, so its nucleus contains 14 protons
no. of protons + no. of neutrons = atomic mass number
p + n = A
14 + n = 28
n = 28 - 14 = 14
An atom of Si-28 contains 14 neutrons.
Answer:
0.174 M
Explanation:
The same can be solve by using Nernst's equation
The Nernst's equation is:
For silver cell
n= 1
As both the compartments have silver nitrate solution,t the standard emf of cell will be zero.
Given
Ecell = 0.045
[Anodic compartment]= 1 M
Putting values
Taking antilog and solving
[AgNO3]=0.174 M
