Indicate whether each of the following samples of matter is a heterogeneous, homogeneous mixture, element or compound A. A colorless gas, only part of which reacts with hot iron B. A uniform red liquid with a boiling point of 60 degrees C that cannot be broken down into simpler substances using chemical means C. A yellow solid all or which melts at a temperature of 45 degrees C to produce a liquid that decomposes upon further heating D. A single phase liquid that completely evaporates without decomposition when heated to produce a gas that can be seperated into sinpler components using physical means
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
