Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

Percent Composition Report Hypothesis : By using seperation techniques properly‚ the 3 substance such as; water‚ sand‚ and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent

I. Introduction The Percent Yield lab is designed to further the students’ understanding of percent yield by having them predict how much material will be produced from a reaction; specifically a double replacement reaction. In order to perform the lab‚ a solid understanding of percent yield is necessary. According to Prentice Hall Chemistry book‚ percent yield is comprised of two main components. The first is the theoretical yield. The theoretical yield is what is calculated and predicted. It is

today’s society‚ salt is a bad thing. Consuming salt is terrible for your health. If someone says they are salty‚ it means they are angry. Salt is mentioned all throughout the Bible. The gospels of Mark‚ Matthew‚ and Luke all share the same tale concerning salt in periscope 132 of the gospel parallels. After reading the salt verses‚ one may become inherently confused given the seasoning’s reputation in today’s society. Jesus wants us to be salty? Knowing the importance of salt in Jesus’ time

Case Study : Morton Salt 1. Briefly describe salt production‚ from brine production to finished round cans. Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns‚ allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid‚ resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce

Curing Salt / Prague Powder‚ Composition and Safety Issues Posted on August 24‚ 2010 by marvin A sausage is not a sausage without the curing salt. The same is true with tocino‚ it may look like it but taste will be different. Prague powder or curing salt is responsible for giving the processed meat product it characteristic flavor and color. Try to make tocino without prague powder. Drop me a comment‚ if you prove me wrong. It also function as preservative. A substance that kills spoilage bacteria

presentation entitled "The Environmental Impacts of Chemical Deicers and Road Salt". I was required to attend this presentation for my Environmental Issues class as well. The presentation was approximately 25 minutes long and included a powerpoint presentation. In the presentation itself‚ it stated the impacts of road salts and deicers‚ the state uses on the roadways during the winter months. The most commonly used road salt is sodium chloride‚ which is also the most inexpensive and readily available

luck is more important. I totally agree with the quotation‚ because I believe that success comes from hard work‚ as Newton said “Genius is one percent inspiration and ninety nine percent perspiration”. People often believe that luck is something that is beyond our control. How can we know when we get a big contract? How can we predict when our experiment give way for a new discovery? I disagree with this kind of belief. In my opinion‚ luck is the combination of events that occurs on a basis of
