| Experiment 2 | Calorimetry | | Chemistry 1310 | 7/21/2013 | | This experiment is to calibrate a constant pressure calorimeter to experimentally determine a series of heats of reaction that will be used to predict the enthalpy of reaction for another reaction using Hess’ Law and to determine heats of dissolution for a number of ionic salts that will be used to predict lattice energy again by using Hess’ Law. Heat may increase during experiment and undergo exothermic reaction

Jarriette kenn D Patenio Jaymar patana Job madronal Do all ideal gases have the same molar volume? An ideal gas has the following equation of state (an equation which relates various thermodynamic properties for a substance‚ such as pressure‚ temperature and molar volume): Pv = RT P - pressure v - molar volume R - universal gas constant T - absolute temperature Clearly the molar volume depends on temperature and pressure‚ so if two gases are at different conditions then they

Research The Chemical name for Baking Soda: Baking soda is sodium bicarbonate. The molecular formula of sodium bicarbonate is NaHCO3. What Baking Powder contains: Baking powder is a raising agent that is commonly used in cake-making. It is made from an alkali- bicarbonate of soda‚ and an acid- cream of tartar‚ plus a filler like corn flour or rice flour which absorbs moisture. Baking powder is a mixture of leavening agents (baking soda‚ acid salts) and inert ingredients (cornstarch‚ calcium

EXPERIMENT 4B: THE MENDELEEV LAB OF 1869 Materials: 30 element cards‚ periodic table Aim: How can we identify elements based on their propeties? Background: Russian chemist Dmitri Mendeleev is generally credited as being the first chemist to observe patterns emerge when the elements are arranged according to their properties. Mendeleev’s arrangement of the elements was unique because he left blank spaces for elements that he claimed were undiscovered as of 1869. Mendeleev was so confident

Dear Chris Prangel‚ Regarding whether Mountain Man Brewing Company should introduce Mountain Man Light beer to their product line I think it should. Mountain Man has customers who are loyal to it their original product‚ and I don’t think the addition of a new product would affect this loyalty if introduced in the right way. Marketing Mountain Man Light will be where MMBC could preserve the brand name of Mountain Man Lager. Separating the two beverages consistently in the ad campaign in ways
