Experiment 5: VARIATIONS IN PROPERTIES IN THE THIRD ROW OF THE PERIODIC TABLE INTRODUCTION The periodic table is a tabular display of the chemical elements‚ organized on the basis of their atomic numbers and chemical properties. Elements are presented in increasing atomic number. Elements with the same number of valence electrons are kept together in groups‚ such as the halogens and the noble gases. Due to this‚ there are gaps that form four distinct rectangular areas or blocks. The f-block

The Importance of Childhood Vaccinations All babies are born with a small natural immunity to disease‚ but vaccination/immunizations offer important complementary defense against serious infectious diseases. Infectious diseases are also the leading cause death and disability in children. For hundreds of years‚ beginning with Edward Jenner’s research‚ scientists have sought to intervene to prevent the spread of infection by inducing immunity through the use of vaccines. Subsequently‚ scientists

Examination of the Effects of Inhibitory and Non-Inhibitory Competition‚ Enzyme-Substrate Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline

The Effect of The Construction of The Reservoir to the Environment A very good morning to our lecturer‚ Mr. Koh‚ and all my fellow friend. Nowadays‚ the number of the construction of reservoir is keep increase which the total of the flooding area of the reservoir now is up to 400‚000 〖km〗^2. The reasons for the construction of the reservoir had been related to the needs of the consuming of water by the all the people in the world nowadays. The water is used for many reasons such as for drinking
