Introduction: An antacid tablet contains citric acid and sodium bicarbonate (baking soda). When you drop the tablet in liquid, the acid and the baking soda react – this produces the fizz. 3 HCO3-1(aq) + H3C6H5O7 (aq)  3 CO2 (g) + 3 H2O + C6H5O7-3(aq) bicarbonate ion citric acid citrate ion Several factors affect the rate of a reaction. In this investigation, you will design experiments to test three factors that may affect the...

Purpose This experiment was conducted to determine the unknown concentration of a solution of sodium hydroxide by titration. The volumetric method of analysis was to use Oxalic acid solution with known concentration. The oxalic acid to be used in this solution was to be prepared using a given mass of the substance and measuring the volume of the aqueous solution of this solid. Background Information Titration is a quantitative method used in the determination of the quantity of one substan...

In this exploration you will be examining the most common nuclear reaction in star, the Proton- proton chain. This is in the OpenStax textbook on page: 568, 570, 584 See the video of the Animation posted on d2l. OR Download the zip file that contains all the ‘Class Action’ animations.

Model 1. Protein is present on every nutrition label, and part of many of the foods we eat. Eggs are rich in protein, so are all types of meats, even wheat flour is composed of 7-15% protein (the remaining ~70-80% is starch). The “protein” on a nutrition label represents a mixture of many different types of individual protein molecules (for a lesson on mixtures – see activity 3). Any individual protein is a large molecule, which is sometime called a macromolecule. A protein is a macro...

Question 1 An effective hearing conservation program should involve the first defense line, which involves administrative and engineering controls (Bessette, 2017). If the first line of defense fails, an employee-oriented program will mitigate the risks of noise exposure in the workplace. The program should entail an instruction that workers should wear protective equipment when the noise exposure levels are equivalent or over 85dBA.
