PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

Determination of Calcium ions in milk using titration. Background Calcium is a mineral which is essential to the human body. In fact 1.5% of the human body is made up of calcium‚ and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions‚ for example blood clotting. It also partakes in the regulation of the hearts rhythm. Lack of the crucial mineral can result in the build up of cadmium and lead‚ both of which are toxic. along

CUP OF LAVA Camille Sager Darielle Donato Eric Valerio I. Introduction Salt‚ also known as common salt‚ table salt‚ rock salt‚ or halite‚ is an ionic compound with the formula NaCl (sodium+chloride). Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. Because of its importance to survival‚ salt has often

result of the chemical reaction to be a moisturizer soap. First‚ our main ingredient to make a moisturizer soap is the Broccoli plant and second Fatty acids‚ and there lots of type of oils but we will use only the Coconut oil. Then‚ we will also need a Sodium Hydroxide (NaOH) or also can be called Lye or Caustic Soda. The Lye is dissolve in liquid water and adds into the Coconut oil and your Broccoli too. And when those three different types of ingredient combines together it starts the process called

Reaction rate = fixed amount of reaction time taken time taken From this we can see that the reaction rate is proportional to l ÷ time. THE DISAPPEARING CROSS The reaction used in this experiment is between dilute hydrochloric acid and sodium thiosulphate (formula Na2S2O3). You can see from the chemical equation below that one of the products is sulphur‚ which does not dissolve in water. [pic] As the reaction proceeds‚ a fine precipitate of sulphur forms‚ which makes the water go

they probably would state with the Periodic Table. The Periodic Table consists of many elements‚ for instance: Sodium (Na) is a metal‚ which is located in group 1‚ period 3‚ with an atomic number 11 and has a mass of 22.99. Chlorine (Cl) a nonmetal located in group 7A‚ also in period 3‚ with atomic number 17‚ and a mass of 35.45. When these two elements are put together‚ they make Sodium Chloride (NaCl)‚ which is table salt that people use every day. In the periodic table‚ there are many different
