PROJECT IN CHEM LAB. Submitted by: BHEA MARIE MENDOZA Submitted to: -CATIONS and ANIONS- Cations are positive charged ions. A cation has fewer electrons than protons. Anions are negatively charged ions. An anion has more electron than protons. The nature and magnitude of charge on ion depend on the position of an element in the periodic table. In forming an ion‚ an atom of a main group element loses gains electrons to obtain the electronic configuration of the noble gas

By the year 2050 the world’s population will reach 9.1 million. In order to feed this larger population food production must increase. And it demands high crop yield to provide food for all. For this purpose the use of chemical fertilizers and pesticides has been very high. Though satisfactory crop yield is obtained by the application of chemical fertilizers and pesticides‚ their use brings out certain disadvantages. These include pollution of large water resources‚ destruction of microorganisms

Vertical farming is cultivating plant or animal life within skyscrapers or on vertically inclined surfaces. The idea of a vertical farm has existed at least since the Hanging Gardens of Babylon. A vertical farm would be a large‚ independently operating structure centrally located in a major city. It would feature two multi-storey‚ skyscraper-like buildings working together- one to manage food production with nutrient film techniques‚ and another to manage waste through living machines and generate

Colligative Properties The Physical Properties of Solutions Colligative Properties • There are 3 colligative or physical properties of solutions that you should know. They are Vapor pressure Boiling point elevation Freezing point depression Osmotic pressure is one you don’t need to worry about. 1. 2. 3. 4. Molality • Molality measures the moles of solute dissolved in the mass (kg) of solvent. • Molality normally expresses concentrations of colloids. • m = moles solute kg solvent

Fuel From Plastic Waste Introduction: Household items made of various kinds of plastic. Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass‚ and may contain other substances to improve performance and/or reduce costs. Monomers of Plastic are either natural or synthetic organic compounds. The word is derived from the Greek

Cell Osmotic Fragility‚ Solute Permeability and Diffusion Potentials of Permeable Membranes Introduction This experiment examines cell membrane permeability‚ osmosis and membrane voltages; all of which are important in understanding how cells are affected by their environment. The movement of water across membranes is important for cell volume and thus the volume of extracellular compartments. The mechanisms for solute transport are essential in maintaining cell functions and homeostasis. Furthermore

Mass production of food and the effect on its consumers and the community. Mass production of food and the effect on its consumers Abstract Where does the food we consume come from? We go to the grocery store and always know that the products we want will be there. Nothing runs out and we can pick up whatever we need. Meat‚ eggs‚ produce and even convenient frozen pre-made meals. But before we pick it up in the grocery store we never see
