Which of the following is an incorrect statement on mass? * All statements are correct. Mass is anything that occupies space and has weight. Mass is the measurement of the amount of matter in an object. O Mass can be expressed in kg, cg, pound mass, and slug, among others. Which of the following is a true and correct statement on volume? * O volume can be computed by the ratio of mass and volume. O volume can be expressed in L, gal, mL, dB, and cubic feet, among others. O volume is the measurement of the amount of density an object occupies. Volume is directly measured in the laboratory by using specialized glassware like the graduated cylinder and the pipet.

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.
