Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a

William ‘Bill’ Shakespeare’s The Tragedy of Hamlet‚ King of Denmark‚ a turn of the 16th century revenge tragedy play‚ is today still a relevant and delving tale‚ that stands as Bill’s reconceptualization of the genre. The genre was popular at the time of Hamlet’s creation‚ and thereby retains traditional elements of a revenge tragedy. However‚ and after adding many dramatic elements‚ a flicker of an Oedipus complex‚ and a touch of humor‚ Bill analyses and explores the revenge tragedy on a more complex

Aim: To examine a number of different chemical reactions and determine if they are exothermic or endothermic. Apparatus: • Test tubes {Around 10-12 in number} • Test-tube rack • Spatula • Digital thermometer { ± 0.1° C} • Digital balance {± 0.01 g} • Measuring cylinder {± 0.5cm³} • Different chemicals Introduction/Theory: Exothermic reactions are those reactions that release energy in the form of heat. Endothermic reactions need to absorb energy in the form

Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group.

Alana Rogers Date of experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble

Argon (Ar) is a noble gas found in Group 0 on the periodic table. It gets its name because of its chemical inertness and comes from the Greek root ‘Argo‚’ which means lazy. This is because Argon doesn’t react well with other elements. The atomic number of Argon is 18 making it a member of the helium group of elements which are also called noble‚ or inert‚ gasses and are non reactive. Its electronic configuration is: 1s2 2s2 2p6 3s2 3p6 The outermost shell‚ shell number three‚ has a completely
