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

up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction‚ they

ability to open to release water. Factors effecting rate of osmosisOsmotic pressureOsmotic pressure is the pressure caused by the difference of solute concentration between solutions separated by a semi-permeable membrane. As osmosis takes place pressure builds up on the side of the membrane where the solvent concentration has increased. This pressure prevents more water from entering the membrane and osmosis stops.PermeabilityPermeability affects the rate of osmosis because if a material is permeable

Chemistry 12 Formal Report Measuring Reaction Rate using Volume of Gas Produced By John Doe 23th October 2012 Introduction An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding. Many factors effect reaction rates‚ two shown above include temperature and concentration. Concentration affects the

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

launch of a new on-line bookstore‚ on-line banking and in 1999 mobile phones were on the shelves of the stores. Tesco has come a long way since its early years; it has gone from just selling your average groceries to banking and insurance. For example‚ in 2005 they announced annual profits of £2 billion and most recently in 2009 Tesco launched tesco.com/clothing and in 2010 – Tesco opened the world’s first zero-carbon supermarket in Ramsey‚ Cambridgeshire. 1 The Tesco Logo Tesco is well known

possessions. The novel and play are very different as the play ‘Macbeth’ concentrates on speech and how Lady Macbeth uses speech against people. Plays rely on speech to convey emotions and roles to the audience which really demonstrates the character. For example‚ “looks like the innocent flower‚ but be the serpent under it”. This quote shows how speech is important in plays because the reader would have to infer the speech‚ therefore this shows that speech is emphasised more‚ than Lady Macbeth’s body language
