Answer 1

Given:

Sugar solution, air, copper, silver, gold, water, glucose, oxygen gas, hydrogen. ammonia, carbon dioxide, smoke, dust, brass, soap solution, bronze

To find:

Estimate total number of wre substances = x (11) Homogeneous mixtures = y (iii) Heterogeneous mixture = z.

Find x - z + y

Solution:

From given, the homogeneous and heterogeneous mixtures are:

1. Sugar solution - z

2. Air - y

3. Copper - y

4. Silver - y

5. Gold - y

6. Water - y

7. Glucose - y

8. Oxygen gas - y

9. Hydrogen - y

10. Ammonia - y

11. Carbon dioxide - y

12. Smoke - z

13. Dust - z

14. Brass - y

15. Soap solution - z

16. Bronze - y

Therefore, we have,

The total number of substances x = 16

The homogeneous mixtures y = 12 and

The heterogeneous mixtures z = 4

so, now consider,

x - z + y

= 16 - 4 + 12

= 12 + 12

= 24

= 2 + 4

= 6

∴ The value of x - z + y = 6
