I. BACKGROUND Precious metals and gemstones have been a popular investment vehicle especially in Asian countries and on the part of those who are constantly moving from one country to another. Asians have a special fondness for them because precious metals and gemstones have enabled them to survive hard times most especially when the super power waged their wars on our shores. Another reason for this is the presence of many gold deposits and mines in our country

Aluminum GuttersOf all the types of gutters to choose from‚ there is a very good reason why aluminum dominates the gutter market. The metal is corrosion-resistant‚ lightweight‚ easy to work with‚ available in wide range of colors‚ and less expensive than the other alternatives. Copper GuttersCopper gutters will not hold up that much better or last longer than aluminum gutters for the added cost. There are certain long term and short term advantages to copper gutters‚ as long as they are installed

Lab 1: Determination of the Empirical Formula of Silver Oxide Lab Objective: In this experiment‚ the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen‚ and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of Lab Procedure: 1. Set up Bunsen burner on a ring stand beneath and clay triangle

Report on High Entropy Alloys(HEA) Introduction: Alloys can be defined as a mixture of two or more elements containing one or more elements containing one metal at the least. From bronze age ‚ alloys have been developed based on one principal element. Later metal matrix composites and inter metallic compounds gained attention. Development in technology and innovation lead to the idea of multicomponent system. These systems consists of multiple principal elements. This was attained by alloying

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them
