Two different images showing different arrangement of particles is given. The class of matter (an element, a compound, a homogenous mixture, or a heterogeneous mixture) and the physical state in the given images is to be stated. Concept introduction: The space between the particles of solids is very less, so they just vibrate at their own place, while the specie between the particles of liquid is more as compared to solids. The space between particles of gas is very large so they can easily move and collide with each other and with the walls of the container. Large space between the gaseous particles makes them highly compressible in nature. When the atoms belonging to different elements are chemically combined in a fixed ratio then it leads to the formation of a compound while when the atoms of same type are combined together then it leads to the formation of an element. The homogeneous mixture consists of same uniform composition and appearance throughout the mixture while the heterogeneous mixture has non-uniform composition throughout the mixture. To determine: The class of matter (an element, a compound, a homogenous mixture, or a heterogeneous mixture) and the physical state in the given image.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve both parts of the same long problem.
