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

ToK: Sense Perception Essay Perception can be defined as one’s opinion and one’s interpretation. One of the forms of perception is sense perception‚ which is based on the usage of our five senses; the five senses being the ability to taste‚ touch‚ hear‚ see‚ and smell. The sense of taste allows us to differentiate and categorize sweet‚ sour‚ bitter‚ and salty. Touch gives us the ability to tell the difference of textures. The ability to hear allows us to identify sounds and speech‚ which plays

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

The taste of food is affective to your feeling and health. Because it is very importance for life‚ you need it every times. Knowing how to make your food taste good is very necessary for wife houses and worker‚ especially‚ for general people. For my idea‚ there are three thing can make your food taste good.

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

Title: TOK Essay 1/2012 Question: When should we trust our senses to give us truth? Name: Syaza Yasirah Bte Abu Bakar Class: P2 Index number: 14 Word Count: 1439 The Ways of Knowing of sense is related to empirical observation. From empiricism we might get facts‚ knowledge and truth. In this case‚ when our senses are reliable‚ it is defined as trust. Truth can be determined based on the three theories of truth. Although none of them is entirely satisfactory‚ each of the theories
