The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.16 g/mL. A 3.616 g glass fragment was recovered from a suspect's clothing. When the fragment was placed into a graduated cylinder filled with water, 1.58 mL of the water was displaced. Calculate the density of the glass fragment. Does the glass fragment that was found in the suspect's clothing link him to the crime scene? not enough information to determine no yes
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.
