Experiment # 4: Analysis of Soda Ash Experiment # 5: Volumetric Analysis of a Carbonate – Bicarbonate Mixture Submitted by: Eugenio December 2012 Department of Chemical Engineering University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also

sun all year round? Luckily for those of us who don’t live at the beach‚ using an indoor tanning lotion when we tan indoors can help us maintain a beautiful tan all the time. This type of tanning lotion is not to be confused with a bronzer or a sun block. A bronzer works by providing immediate color to the skin‚ while a sun block protects the skin from the harmful effects of the sun. This type of lotion on the other hand‚ works with indoor tanning beds in accelerating the production of melanin in your

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic

Intro The emerald ash borer is an invasive wood boring insect that originated in Asia. The borer is believed to have crossed the Canadian and American border in the early 2000s by way of Windsor and Detroit (1). They have now infested much of Southern Ontario‚ as well as‚ in small parts of western Quebec (2). Emerald ash borers destroy ash trees by eating all the ash species in Ontario which include green‚ red‚ white‚ black‚ and ash trees. When beetles eat ash trees‚ they leave 4-5 millimeter holes

Fibers are uniformly distributed throughout the matrix. Perfect bonding between fibers and matrix. Matrix is free of voids. Applied loads are either parallel or normal to the fiber direction. Lamina is initially in a stress-free state (no residual stresses). Fiber and matrix behave as linearly elastic materials. Longitudinal Modulus Equal strain

Separation of Mixtures Mixtures exist in many forms in the world‚ and if it were not for methods of separation‚ many of these substances would be meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation
