Solid gold (III) oxide undergoes a thermal decomposition reaction to form gold metal and oxygen gas. 1. Write the balanced equation for this reaction, including physical states.
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.
Solid gold (III) oxide undergoes a thermal decomposition reaction to form gold metal and oxygen gas.
1. Write the balanced equation for this reaction, including physical states.
2. This reaction will go to completion without the need for a catalyst like MnO2 with potassium chlorate. Based on this information, which element, gold or chlorine, more readily is reduced in these reactions? Explain.
3. When a student was completing this experiment, the atmospheric pressure was measured to be 751 torr. The temperature of the water was found to be 23.0°C. What is the pressure (in torr) of the oxygen gas, PO2, that is produced?
