A 250 mL beaker is filled with 100 mL of a 0.30 M solution of acetic acid (CH3COOH) and 150 mL of a 0.10 M solution of sodium hydroxide. Acetic acid is a weak acid and all solutions have been prepared in water. Which beaker diagram is the best representation of the solution obtained after the reaction is complete Legend: Na o CH₂COO CH₂COOH H₂O o
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.
