Given :
Two chemicals and .
To Find :
Are these substances same or different explain.
Solution :
It might seem that the difference is none because the atoms used in the molecules are same but in different proportion .
But , their is a lot of difference between them .
The change in configuration impacts a lot in physical as well as chemical properties .
For ex :
is red powder while is black powder .
is fungicide while is used in batteries .
Hence , this the required solution .
Answer:One mole of HBr has 6.02 x 1
0
23
molecules of HBr.
1 mole of HBr = 6.02 x 1
0
23
molecules of HBr.-----(a)
X mole of HBr has 1.21 x
10
24
molecules of HBr.
X mole of HBr = 1.21 x
10
24
molecules of HBr------(b)
Taking ratio of (a) and (b)
X / 1 = 1.21 x
10
24
/ 6.02 x 1
0
23
X= 2.009 moles.
Explanation:
Alrighty, so, imagine you didn't or don't know much about desertification. You could imagine that it means the land becomes a desert.
