A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or

Angela Adivoso Ayala Museum Reaction Paper On the 9th of February‚ I visited the Ayala Museum with the company of my mother and a friend‚ in the hopes that I could see some extraordinary things from our country’s (and as well as some parts of Asia’s) past – things that we do not see inside the classroom. To get this show on the road‚ I think it would be best to begin by saying that I was not at all disappointed. Starting from the grand lobby of the building‚ we made

Reaction on Climate Change The Philippines has been considered as a highly vulnerable to current (natural disasters)‚ as well as future climate-related risks due to its geographical location and physical characteristics. It lies along the Western Pacific Basin (a generator of climatic conditions such as monsoons‚ thunderstorms‚ Inter-Tropical Convergence Zone‚ typhoons‚ among others) making it a path of an average of 20 tropical cyclones annually‚ nine of which makes a landfall.

Reaction Paper about Honor and Excellence The speech of Prof. Monsod‚ a retired professor in college of economics in the University of the Philippines gave her last lecture to her students about the motto of the university. In her lecture‚ she urged her students to place honor and excellence‚ in which I agree that honor‚ was placed first before excellence for a reason. It is interesting that Prof. Monsod pointed out cheating. She added that cheating in small thing would

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this
