Computer The Determination of a Chemical Formula 1 Second‚ you will conduct a chemical reaction with the dried sample‚ which will produce elemental copper. By measuring the mass of copper that forms‚ you will have the necessary information to determine the moles of copper and chlorine in your sample‚ and you will be able to establish the proper chemical formula. OBJECTIVES • • • In this experiment‚ you will Ev al Determine the water of hydration in a copper chloride hydrate

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Experiment In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin‚ I first gathered everything‚ including the 96 well plate‚ 24 well plate‚ goggles‚ and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next‚ I made my data table so that I could record my reactions
