Answer 1

Answer:

Step-by-step explanation:

Hi there here we have,

(i) 12321

So, if a number is divisible by 11,

We need to add alternative numbers and either add them or subtract them and check whether the answer is 11 or 0.

So,

1+3+1 = 5 & 2+2 = 4

=> 5+4 = 9 or 5-4 = 1

So, 12321 is not divisible by 11.

Now, we need to check for 9.

If a number is divisible by 9, we should add all the digits and divide it by 9 and see whether it is a whole number.

So,

1+2+3+2+1 = 9

9/9 = 1

So, 12321 is divisible by 9.

(ii) 8019

So, if a number is divisible by 11,

We need to add alternative numbers and either add them or subtract them and check whether the answer is 11 or 0.

8+1 = 9 and 0+9 = 9

So, 9+9 = 18 or 9-9 = 0

Since we have 0, 8019 is divisible by 11.

Now, we need to check for 9.

If a number is divisible by 9, we should add all the digits and divide it by 9 and see whether it is a whole number.

So,

8+0+1+9 = 18

18/9 = 2

Since the answer is a whole number,

8019 is divisible by 9.

(iii) 6561

So, if a number is divisible by 11,

We need to add alternative numbers and either add them or subtract them and check whether the answer is 11 or 0.

So,

6+6 = 12 and 5+1 = 6

So, 12 - 6 = 6 or 12+6 = 18

So, 6561 is not divisible by 11.

Now, we need to check for 9.

If a number is divisible by 9, we should add all the digits and divide it by 9 and see whether it is a whole number.

So,

6+5+6+1 = 18

18/9 = 2

Since the answer is a whole number,

6561 is divisible by 9.

(iv) 8404

So, if a number is divisible by 11,

We need to add alternative numbers and either add them or subtract them and check whether the answer is 11 or 0.

So,

8+0 = 8 and 4+4 = 8

=> 8+8 = 16 or 8-8 = 0

Since we get 0, 8404 is divisible by 11.

Now, we need to check for 9.

If a number is divisible by 9, we should add all the digits and divide it by 9 and see whether it is a whole number.

So,

8+4+0+4 = 16.

16/9 = 1.77

Since the answer is not a whole number,

8404 is not divisible by 9.

Hope this helps you,

Answer 2

Answer:

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Wikipedia
