There are two kinds of mixtures

a) homogeneous : the boundary of the two components is not physically distinct

b) heterogeneous:the boundary of the two components is  physically distinct

the following separation techniques are common for mixtures

1) filtration: if the two components are forming heterogeneous mixture we can separate them by filtration.

2) boiling: if boiling point of one of the components is less than other

3) magnetic separation: if one of the component is magnetic

4)sieve method: for solid components with difference in size of particles

5) hand picking

Thus the correct match will be as shown in the figure

If a gold bar is 16,000 g mass and 800 cm^3 volume what is the density?
ki77a [65]

Answer:

<h3>The answer is 20 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 16,000 g

volume = 800 cm³

We have

density =  \frac{16000}{800}  =  \frac{160}{8}  \\

We have the final answer as

<h3>20 g/cm³</h3>

Hope this helps you
