I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance which allows it to behave in a specific manner. A few types of chemical properties are combustibility
