Tashia & Tobi Lab Report experiemt 5 INTRODUCTION In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got

July 14‚ 2009 Experiment 6: Fractional Distillation. Separation of Petroleum Hydrocarbons Abstract: A mixture of cyclohexane and toluene were separate from one another by fractional distillation in order to measure the composition of each fraction and prepare the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application

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

Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are

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
