The prime factorization of 11008 is
2|11008
2|5504
2|2752
2|1376
2|688
2|344
2|172
2|86
43|43
1
11008=2×2×2×2×2×2×2×2×43
11008=2^8×43
The prime factorization of 7344 is
2|7344
2|3672
2|1836
2|918
3|459
3|153
3|51
17|17
1
7344=2×2×2×2×3×3×3×17
7344=2^4×3^3×17
Now, HCF=Product of the smallest power of each common
prime factor in the numbers.
HCF=2^4=16
LCM = Product of the greatest power of each prime factor,
involved in the numbers.
LCM=2^8×43×3^3×17=256×43×27×17=5052672

The mole concept is a convenient method of expressing the amount of a substance. Any measurement can be broken down into two parts – the numerical magnitude and the units that the magnitude is expressed in. For example, when the mass of a ball is measured to be 2 kilograms, the magnitude is ‘2’ and the unit is ‘kilogram’.

Any positive integer is of the form 5q , 5q + 1 , 5q + 2
here ,
b = 5
r = 0 , 1 , 2 , 3 , 4
when r = 0 , n = 5q
n = 5q ----> divisible by 5 ===> [1]
n + 4 = 5q + 4 [ not divisible by 5 ]
n + 8 = 5q + 8 [ not divisible by 5 ]
n + 6 = 5q + 6 [ not divisible by 5 ]
n + 12 = 5q + 12 [ not divisible by 5 ]
-------------------------------------------
when r = 1 , n = 5q + 1
n = 5q + 1 [ not divisible by 5 ]
n + 4 = 5q + 5 = 5 [q+ 1] ----> divisible by 5 ===> [2]
n + 8 = 5q + 9 [ not divisible by 5 ]
n + 6 = 5q + 7 [ not divisible by 5 ]
n + 12 = 5q + 13 [ not divisible by 5 ]
----------------------------------------------
when r = 2 , n = 5q + 2
n = 5q + 2 [ not divisible by 5 ]
n + 4 = 5q + 6 [ not divisible by 5 ]
n + 8 = 5q +10 = 5 [q + 2 ] ---> divisible by 5 ====> [3]
n + 6 = 5q +8 [ not divisible by 5 ]
n + 12 = 5q + 14 [ not divisible by 5 ]
----------------------------------------
when r = 3 , n = 5q + 3
n = 5q + 3 [ not divisible by 5 ]
n + 4 = 5q + 7 [ not divisible by 5 ]
n + 8 = 5q + 11 [ not divisible by 5 ]
n + 6 = 5q + 9 [ not divisible by 5 ]
n + 12 = 5q + 15 = 5 [ q + 3 ] ---> divisible by 5 ====> [4]
----------------------------------------------------
when r = 4 , n = 5q + 4
n = 5q + 4 [ not divisible by 5 ]
n + 4 = 5q + 8 [ not divisible by 5 ]
n + 8 = 5q + 12 [ not divisible by 5 ]
n + 6 = 5q + 10 = 5 [ q + 2 ] ---> divisible by 5 ====> [5]
n + 12 = 5q + 16 [ not divisible by 5 ]
from 1 , 2 , 3 , 4 , 5 its clear that one and only one out of n, n+4, n+8, n+12 and n+6 is divisible by 5

When solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride.
<i>BaCl2 + Na2SO4 </i>→ <i>BaSO4 + 2NaCl</i>
When sodium hydroxide (a base) reacts with hydrochloric acid, sodium chloride and water are formed.
<i>NaOH + HCl </i>→<i> NaCl + H2O</i>
