Chapter I. BACKGROUND OF THE STUDY Charcoal one of the earliest known forms of ink‚ was used as early as 30‚000 BC. The first of its use documented in the continent of Europe. It may be a bit primitive to these modern times but still very useable for those who want to try it. The recipe of making it however is similar to those inks made by ancient civilizations such as the ink used by the Ancient Egyptians. We propose to make charcoal ink as a statement to increase of those in the Philippines who

There are many chemicals in our world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch

• Incensement of total capacity of treatment plant and improvement to water quality can be achieved vary easily. It’s possible due to lamella settlers‚ which provide high treatment in smaller footprint and high degree of settling capacity also process is more efficient and faster than conventional treatment with sedimentation tank. That because of one of most important feature of lamella settlers‚ are series of inclined plate which the suspended particles goes down with water flow‚ where solid particles

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

Project Paper Name Institution Introduction swimmers are frequently advised to leave the water after strikes of lightening. What is the scientific basis for this? What property of water makes swimmers corned when electricity is around? What other liquids possess the same property? Does distilled water behave the same? Consider the following; a. What takes place when a solute dissolves in a solvent? How would this be determined? b. What process in the molecular level takes place to explain what is

* Introduction The melting point is defined as the temperature at which the solid is in equilibrium with its liquid‚ and this characteristic is very unique‚ so a substance can be determined by the melting point. Determination of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and

Differential Scanning Calorimetry (DSC) was carried out to investigate the thermodynamic properties of CXB‚ different carriers‚ PMs and SD preparations. Their thermograms are represented in Figures (9-14). The thermogram of CXB in Figure (9) was characterized by single‚ sharp endothermic peak at 165±0.56°C which represents the melting point of CXB. Some researchers reported that CXB melting point ranging from 160.79–164.64°C (127)‚ and Paradkar A. et al. (2002) reported that sharp endotherm corresponding

In simple terms‚ secondary recovery is the addition of basic water flood or gas flood (i.e.‚ pressure maintenance) as a continuous force. Secondary recovery methods should be introduced very early in the life of a field while the income and profits from the wells are high enough to pay for the additional equipment and installation costs. As noted in the following sections‚ there
