CHAPTER # 1 Q.DEFINE CHEMISTRY. A. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with the interactions between atoms and various forms of energy Q.DEFINE THE BRANCHES OF CHEMISTRY. * Physical chemistry is the study of macroscopic‚ atomic‚ subatomic‚ and particulate phenomena

the Rate of Reaction Between HCl and Sodium Thiosulfate Chemistry Lab report Aim: The aim of this experiment is to determine how concentrations of HCl acid affect the rate of reaction when reacted with Sodium Thiosulfate (Na2S2O3). This experiment would require measuring the mass of the reaction over a period of time to be able to determine the rate of the reaction. Safety Precautions: In this experiment‚ SO2 gas is produced from the reaction between Sodium Thiosulfate and HCl‚ and this can be dangerous

Chemistry Coursework – Titration Background Science A titration is the neutralisation of an acid or an alkali. To achieve this‚ one must be added to the other in a specific amount‚ strength and concentration. A substance is neutral when its pH is 7. It is most acidic closer to 0 and is most alkaline closer to 14. 28492453194050 0 7 14 595423979670

Abstract By adding HCl to 2-methyl-2-butanol‚ through the Sn1 mechanism‚ 2-chloro-2-methylbutane is formed. Water‚ sodium bicarbonate and NaCl(aq) were then added to the 2-chloro-2-methylbutane to remove any of the excess water from the reaction. To confirm‚ a successful reaction‚ AgNO3 was added to the 2-chloro-2-methylbutane. A white precipitate formation confirmed a successful Sn1 reaction. Introduction Nucleophilic substitution reactions such as Sn1 and Sn2 allow us to convert one functional

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food
