Purpose: During this experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction

In this lab‚ the pH of flat sprite and a fresh sprite are compared two ways: one way was to record the pH directly with a digital pH probe and the other was to calculate the concentration through titration. Because the reaction is a neutralization reaction‚ the concentration of can be calculated if the concentration of is known. At the end of the titration‚ the moles of will equal the moles of and the pH is expected to be greater than 7 because the found in sprite is weak and is a strong

floor‚ the upper part of the other hanger is near the pulley‚ without touching the pulley. (You may find that the lab assistant has already set up the apparatus as described here. If so‚ double check the setup.) 2. Place equal masses of approximately 1000 g on each weight hanger. These masses should include four 5 g masses at the top of the left hanger. Hold back the 1 g and 2 g masses from the weight sets and do not initially use them on the hangers. Move the weights up and down carefully to

was soluble in water as well‚ but it had a very low melting point. All the substances except for sodium carbonate did not pass the requirements‚ and therefore sodium carbonate is the best possible substance. In order to prove this‚ I conducted a lab to determine the solubility‚ conductivity‚ and melting point of each substance. First‚ I made sure to obtain a Bunsen burner‚ evaporating dish‚ ethanol‚ the four substances‚ distilled water‚ conductivity probe‚ wash bottles‚ test tubes‚ and a beaker
