Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

There are eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species

Abstract—We focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches‚ i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter‚ only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the switches are provided by the PWM techniques. Step up or step down DC outputs can be obtained by using suitable

complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out
