It is the sum of internal energy and the product of the pressure and volume of a thermodynamic system. Enthalpy is generally abbreviated with an “H”. It has the dimensions of energy which is in […]

Introduction:In this lab experiment, E. coli bacteria was being transformed with a gene coding for green fluorescent protein, or GFP, in efforts to make the bacteria glow. The method used to transform the E. coli bacteria with the GFP gene was heat shock, the vector used was the pGLO plasmid, containing the GFP gene and […]

As my car rumbled through the familiar silver gates and past the smiling security guards, I could feel myself trying to stifle an inevitable yawn to no avail. I always thought school started too early. The car took a sharp turn to the left, trundled along for a short distance, and screeched to a grinding […]

OBJECTIVES1) To learn the qualitative and quantitative aspects of common laboratory equipment. 2) To expose to the factors that affect the accuracy of an experiment.INTRODUCTIONChemistry is an experimental science. This experiment was introduced to the student about the basic laboratory technique that commonly used when had an experiment in the lab. It is the basic […]

Rate of reaction is affected by some factors such as concentration of reactant.When the concentration of one or more reactants increase, the higher the number of particles in a unit per volume.The frequency of collisions between the particles increases and increases the frequency of effective collisions.Hence, the rate of reaction increases. Besides, the rate of […]

Bioluminescence is light produced by a chemical reaction within a living organism.Bioluminescence is a type of chemi-luminescence, which is simply chemical reaction where light is produced.Chemistry: The chemical reaction that results in bioluminescence requires two unique chemicals: luciferin, photo protein. Luciferin is the compound that actually produces light. In a chemical reaction, luciferin is called […]

FEASIBILITY OF ASH AS A SUBSTITUTE TO COMMERCIAL INKCHAPTER 1INTRODUCTIONToday, the system of education is modernized and majority of the schools uses electronic and digital way of learning. But despite the modernization, the traditional ‘manila paper and marker’ is stile necessary in the process of learning. Just in case the digital technology fails to do […]

The purpose of the volumetric glassware experiment is to study the measurement of the actual volume contents in 3 different types of volumetric glassware (50 ml beaker, 10 ml pipette, 50 ml burette)Theory Analytical chemistry is a science that trying to answer questions (how much of the substance exist in a matter and what is […]
