Analytical chemistry Analytical chemistry is the branch of chemistry that deals with the separation‚ identification and determination of components in a sample. Analytical chemistry can be divided into two branches‚ qualitative and quantitative. Qualitative analysis It deals with the identity of the constituents that are in an analytical sample. Quantitative analysis It deals with the determination of how much of a given substance is in the sample. The quantitative analyses are classified

Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric acid.

contraction. Sodium also helps to keep calcium and other minerals soluble in the blood‚ as well as stimulating the adrenal glands. High sodium levels can cause high blood pressure. Sodium aids in preventing heat prostration or sunstroke Sodium functions with chloride and bicarbonate to maintain a balance of positive and negative ions (electrically charged particles) in our body fluids and tissues. The body receives sodium primarily in the form of table salt (sodium chloride). Sodium‚ the principal extra

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

sugar‚ heart rate‚ and muscle functions. What are good sources of electrolytes? Sodium‚ chloride‚ potassium‚ magnesium‚ calcium‚ and phosphate are all good sources of electrolytes. You can get all of these in the foods you eat daily. Sodium and chloride can be found in table salt. Meat‚ milk‚ fruits‚ and vegetables contain potassium. Your daily intake of calcium should be around 1000 to 1500 mg‚ calcium and phosphate can be found in almost all dairy products. These are all great sources of electrolytes

Equation 2: Ca2+ (aq) + CO32-(aq) → CaCO3 (s) 3. Equation 3: CaCl2 (aq) + M2CO3→ CaCO3 (s) + 2MCl (aq) The precipitated calcium carbonate is then filtered‚ dried‚ and weighed. The moles of calcium carbonate‚ CaCO3‚ are equal to the moles of Group 1 metal carbonate‚ M2CO3‚ added to the original solution. Dividing the mass of the unknown carbonate by the moles of calcium carbonate yields the formula weight‚ and thus the identity‚ of the Group 1 metal carbonate. Experiment Overview The purpose

What is molar mass?Molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical compounds. Molar masses of common chemical compounds that you might find in the chemistry laboratory can range between 18 grams/mole for compounds like water to hundreds of grams per mole for more complex chemical compounds.The lightest possible chemical that one can have under normal conditions is hydrogen gas‚ or H2. There is no limit to how heavy a chemical compound can be - it is not uncommon for macromolecules (large
