Identify the incorrect statement. For a given substance, different mixtures can have different compositions O Compounds cannot be broken down into simpler substances by chemical means. O A solution is a homogeneous mixture. O A heterogeneous mixture has a variable composition throughout. Two or more elements in fixed proportions make up a compound.
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.
