Electric Car Vs Gasoline car Nowadays‚ people are very crazy about having a car and the present scenario provide them with different kind of power transmission engines‚ however‚ the engines based on electrical and gasoline are common. In electrical transmission vehicle‚ there is a set of batteries that provides electricity to the motor. The engine then turns a transmission‚ which turns the wheels. In gas-powered car there is a fuel tank‚ which supplies gasoline to the engine and the engine gives

Heats of Reaction Lab Report Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation. NaOH(s) ( Na+(aq) + OH-(aq) ΔH = -10.6kcal/mol NaOH(s) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -23.9kcal/mol Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -13.3kcal/mol Background: Energy changes occur in all chemical reactions; energy is either absorbed or released. If energy is released in

Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

knee implant. Each has its own benefits and disadvantages‚ because of this each material is utilized for a different part of the knee replacement. The three parts of the knee replacement are depicted in Figure 1 and are the femoral component‚ the plastic surface‚ and the tibial plate. The material that is the best fit to use for a biodegradable friendly knee replacement wouldn’t be a metal‚ though currently most common used‚ because when metals degrade the particles are smaller in size and greater in

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test
