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.
Balance the equation then name both products.
Sucrose reacts with oxygen to form carbon dioxide and water. In the balanced chemical reaction, the number of atoms of each element is equal in the reactants and in the product.
The reaction of sucrose and oxygen is as follows:
The chemical equation is balanced by changing the scalar number for each chemical formula. Simple chemical equations can be balanced by inspection, that is, by trial and error.
To balance the carbon atom we multiply the CO2 by 12:
To balance the hydrogen atoms multiply the water by 11:
Now we balance the oxygen atom for this we multiply the O2 by 12:
