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.
For each of the word equations convert the given word equations to formulas,
balance the equation,
write the Ionic and Net-Ionic equation,

1. 4 manganese(II) sulfate(s) + 6 sodium chloride(aq) + 4 water(l)→ manganese(IV) oxide + dihydrogen sulfide(g) + hydrochloric acid(aq) + sodium sulfate(aq)?
The chemical reaction in which two salts solutions are mixed together and lead to the formation of solid residue is termed as a precipitation reaction. The insoluble residue so formed is called a precipitate. The precipitate formed in the reaction is in accordance with the exchange of ions between the two salt solutions and thus it is considered as the double displacement reaction.
The molecular equation representing the reaction between manganese(II) sulfate and sodium chloride in water is shown below.
The balanced molecular equation is shown as follows.
The precipitate so formed in the reaction is of MnO2. The gas so evolved in the reaction is of H2S.
The given reaction is a kind of ion-exchange reaction which is also named by the double displacement reaction.
