You heat 2.53 grams of metallic mercury in air, which produces 2.73 grams of red-orange residue. Assume that the chemical change is the reaction of the metal with oxygen in the air. What is the mass of oxygen that react? When you strongly heat the red- orange residue, it decomposes to give her back the mercury and release the oxygen, which you collect. What is the mass of oxygen you collected?
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.
