IMP POW 1: The Broken Eggs Problem Statement: A farmer’s cart hits a pothole‚ causing all her eggs to fall out and break. Luckily‚ she is unhurt. To cover the cost of the eggs‚ her insurance agent needs to know how many she had. She can’t remember the number‚ but can remember some problems she had when packing the eggs. When she put the eggs in groups of two to six eggs‚ there was always one left over. However‚ in groups of seven‚ there were none left over. From what she knows‚ how can she figure

To determine the percentage by mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the

OSMOSIS LAB BACKGROUND INFORMATION. Dialysis tubing is being used to model a plasma membrane. Isotonic solutions are solutions that have the same concentration of solutes on both sides of the membrane. Hypertonic solutions are solutions that have more solute to the one with less solute. Hypotonic solution are solutions that have less solute to the one with more solute. RESEARCH QUESTION:which dialysis tubing will gain the distilled water and which one will loss its content

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal cell’s placed in hypotonic solution‚ it begins to swell and then finally lyse; a plant cell placed in this type of solution however‚ is said to be turgid. In isotonic solution‚ the animal cell stays the same (normal)

they do provide some sense of the issues to be faced. Second‚ diet problems that are missing the constraints that force variety into the diet can be terribly embarrassing. It has been said that a hospital in New Orleans ended up with an LP solution to feed each patient only castor oil for dinner because analysts neglected to add constraints forcing a well-rounded diet.

Chapter 1 Preliminaries Questions for Review 1. It is often said that a good theory is one that can be refuted by an empirical‚ data-oriented study. Explain why a theory that cannot be evaluated empirically is not a good theory. A theory is useful only if it succeeds in explaining and predicting the phenomena it was intended to explain. If a theory cannot be evaluated or tested by comparing its predictions to known facts and data‚ then we have no idea whether the theory is valid. If
