using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance which allows it to behave in a specific manner. A few types of chemical properties are combustibility

At approximately 3:45 I‚ David Constancio‚ was called into the cafeteria by the 4th/5th Grade Team Leader‚ Duc-Huy Nguyen to assist with a student. When I arrived in the cafeteria I observed Jocelyn Elizarraras crying while being comforted by her classmates. The TL explained that the boys were being disrespectful towards Jocelyn and she became upset and grabbed a “spork” from the supper and attempted to “stab” her wrist. Another students yelled out‚ “Jocelyn is trying to kill herself!” I took Jocelyn

Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA‚ IIA‚ and IVA. Proper procedures and observations were done to determine the solubility‚ physical state‚ color‚ and appearance of the compounds namely Li2CO3‚ Na2CO3‚ K2CO3‚ CaCO3‚ and BaCO3. The results shows that Li2CO3‚ Na2CO3‚ K2CO3 were soluble in water‚ while MgCO3‚ CaCO3‚and BaCO3 were not soluble. All of these compounds

Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to

Chemical Periodicity Engr. Imelda Galera De La Salle University-Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Chemical periodicity was demonstrated using different samples of elements from Group IA‚ IIA and IVA. These samples are: Li2CO3‚ Na2CO3‚ K2CO3‚ MgCO3‚ CaCO3‚ BaCO3‚ Carbon‚ Tin‚ Silicon and Lead. Each sample was placed in a test tube‚ (one sample and one test tube) and the physical color‚ appearance and state was defined. Water was used to test the solubility of the element

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

Premium Chemical kinetics Rate equation Chemical reaction
Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics
