Explanation:
It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.
Therefore, in one simple cubic unit cell sharing of one atom is only 
.
Hence, the total number of atoms in a unit cell will be as follows.
= 1
Thus, we can conclude that there is 1 calcium atom present in each unit cell.
Answer: Adiabatic process is a process in which <u>heat</u> is constant
Explanation:
The processes in which temperature remains constant is called isothermal process.
The process in which Volume remains constant is called isochoric process.
The process in which pressure remains constant is called isobaric process.
The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.
Thus option d) heat is correct
Main Answer:
Given
pH = -log[H+]
= -log[0.00017]
= 3.769
We know that
pW = pH + pOH
and pW =14
pOH = 14-pH
=14-3.769
=10.231
According to the definition
pOH = -log[OH-]
10.231 = log[OH-]-1
[OH-]= 5.87 x 10-11
Explanation:
What is pH?
pH is defined as the concentration of H+ ion in the solution. If the pH value is less than 7, then the solution will be acidic. If the pH value is greater than 7, then the solution will be basic.
