Name- Qazi Adil BUS 430 Chapter 2 Discussion Case: Coca-Cola’s Water Neutrality Initiative 1. The public issue in this case was concerning the quality of water TCCC was using‚ how safe if was for its consumers‚ and the deprivation of water from local villagers. In this case‚ the stakeholders were concerned with TCCC’s water consumption claiming it deprived local villagers of supplies for drinking water and irrigation‚ and depleting groundwater by its processes. They also raised concerns with the

tetraphenylcyclopentadienone (0.103 g‚ 0.268 mmol) in a small reaction tube with a boiling stick using glass pipettes to form a dark purple soln. The rxn was then lowered into a sand bath and allowed to reflux until color change from dark purple to tan was observed. Upon cooling‚ ethanol (3 mL) was added and the soln was shaken to facilitate combination. The tan soln was then placed in an ice bath to cool for 10 min. The solvent was removed from the solid under vacuum filtration and washed with cold ethanol

ABSTRACT The average concentration of CaCO3 obtained was 212 ppm‚ with a standard deviation of 1 ppt. The results indicate that the unk B tap water can be considered as hard water. INTRODUCTION Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca 2+‚ Mg2+‚ Fe3+‚ SO42-‚ HCO3-. When this water evaporates or boils‚ the difficult to dissolve metal salts remain as a scaly residue. Hard water inhibits the effectiveness of soap and detergents

Introduction Why: The goal of this experiment is to determine the water hardness of the prepared unknown water sample. Determining water hardness is a useful test that measures the quality of water for its household and industrial users. Water’s hardness arises from the presence of metal ions – specifically metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium

The language L = {w|w has even length and an odd number of 0’s } is the intersection of two simpler languages. Construct DFA’s for the simpler languages and then combine them using the idea of a product automaton to obtain a DFA that accepts L.
