 (k) Matter that obeys the law of definite composition

                                                                                    

                               

Step-by-Step Solution

Answer

The depiction of various types of matter on the atomic scale is 

1. Picture D and E
2. Picture I
3. Picture  A
4. Picture H
5. Picture C and H
6. Pictures B and G
7. Pictures B, F and G
8. Picture F
9. Picture D
10. Picture D
11. Picture B and F

Step 1:Mixture that fills its container

Picture D and E both depict a mixture that fills the container. The different coloured atoms indicate that it is a combination, and E is a mixture of gases while D represents a mixture of a liquid and gas.

                           

Step 2:A substance that cannot be broken down into simpler ones

The picture I depicts an element and elements cannot be broken down into simpler substances as it represents a Monoatomic gas.

                                        

Step 3:An element with very high resistance to flow

Solids are the substances which are show resistance to flow and figure A shows a solid, so, An element with very high resistance to flow is shown in figure A.                                    

                                          

Step 4:A homogeneous mixture

The mixture H depicts a homogenous mixture. We see a liquid substance with evenly distributed component dispersion.

                                             

Step 5:An element that conforms to the walls of its container and displays a surface

Both figures C and H represent the liquid state, so these will conforms to the wall of the container.

                               

Step 6:A gas consisting of diatomic particles

Gases shown in B and G are made up of diatomic particles.

                             

Step 7:A gas that can be broken down into simpler substances

Pictures B, H and F represent diatomic and triatomic gases so these can be broken down into simpler substances.

                 

Step 8:A substance with a 2/1 ratio of its component atoms

Picture F depicts a material having a 2/1 ratio of its constituents.                

                                      

Step 9:Matter that can be separated into its component substances by physical means

Picture D represents a heterogeneous mixture and it can only be split into its constituents by physical means.

              

                                           

Step 11:A heterogeneous mixture

Picture D depicts a heterogeneous mixture.                                     

                                     

Step 11:Matter of definite composition that obeys the law

Pictures B and F represent compounds and a compound has a definite composition of its elements. So B and F obey the law of definite composition.
