A crime scene analyst found out a 10 mm thick metal plate was penetrated by 10 bullets that caused a severe but clean volumetric defect in the form of 10 holes with a diameter of 10 mm each. If the theoretical density of the metal plate is 10 g/cm3, how many metal atoms have been removed from the plate due to the impact? Assume a solid structured metal, with an atomic weight of 100 g/mol, Given the Avogadro constant as 6 × 1023 atom/mol and π = 3.14.
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.
