Scenes A-I depict various types of matter on the atomic scale. Choose the correct scene(s) for each of the following:
(a) A mixture that fills its container
(b) A substance that cannot be broken down into simpler ones
(c) An element with very high resistance to flow
(d) A homogeneous mixture
(e) An element that conforms to the walls of its container and displays a surface
(f) A gas consisting of diatomic particles
(g) A gas that can be broken down into simpler substances
(h) A substance with a 2/1 ratio of its component atoms
(i) Matter that can be separated into its component substances by physical means
(j) A heterogeneous mixture
(k) Matter that obeys the law of definite composition

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.

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

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.

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

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

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

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

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

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

Picture D depicts a heterogeneous mixture.

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