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.
Sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas.
Enter a balanced chemical equation for each of the following.
In balanced chemical reaction number of each atom on reactant side is equal to number of each atom on product side. This can be achieved by changing stoichiometry coefficient.
