Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

Fact: Everyone has heard at least one Salt-N-Pepa song. Now‚ hear me out‚ I know you recognize these lyrics: “Let’s talk about sex‚ baby/let’s talk about you and me/let’s talk about all the good things/and the bad things that may be.” That song is appropriately titled “Let’s Talk About Sex‚” and it is a ballad about safe sex and sexual awareness as a whole. Salt‚ Pepa‚ and DJ Spinderella cried out against the lack of conversation about sex in the ‘90s because they believed in normalizing sex‚ especially

Biochemistry Task 5 Shannon Alford Lipid Storage Molecule Conversion to ATP Lipids (also known as fats) are nonpolar‚ insoluble molecules gained within the body trough digestion of food. Triglycerides‚ a type of lipid that serve as storage units for energy have 3 fatty acid chain tails made up of carboxylic acid and a fatty carbon chain attached to a glycerol backbone. These molecules can be saturated or unsaturated contingent on the bond types and hydrogen number in the molecule. Anytime a fatty

Enzymes are biological catalysts‚ large protein proteins that have a very specific three-dimensional shape which makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can

Salt Lake City Best Sports City Without Doubt! While many computer games have turned today’s young ones into small couch potatoes: Salt Lake City Games is looking to change all of that. Wii‚ or just called "Wii" by many folks‚ is an interactive action-based video game you connect to your TV. We asked them to select two (2) athletics to play within an organized league. Here the discipline of the game and learning how to cope properly with adult authority added to their overall increase. Never did

There are a lot of activities to enjoy around us. We are able to divide two type of activities such as indoor activities and outdoor activities. Some people like outdoor activities such as a baseball‚ football. Others like indoor activities such as volleyball‚ table tennis. In case of indoor activities‚ regardless of weather‚ people want to play sports‚ they can enjoy them. However‚ I prefer playing outdoor activities. There are two reasons why I think so. First‚ outdoor activities help people to be

Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases

Discussion: Shown in tables 1 and 2‚ the shoot heights‚ on average‚ of the barley seeds‚ increased as the Aquasol concentration increased. This is with the exception of the solution with an initial Aquasol concentration of 0.40% in Table 1‚ which showed to have‚ on average‚ shorter shoot heights in comparison to the solution with 0.25% Aquasol. Ultimately‚ this indicates that the experiment had random and systematic errors that affected the accuracy‚ reliability‚ validity‚ and precision of the results

According to the results‚ the experimental group had a huge impact when the diluted concentration of caffeine was put in compared to the control group that contained no concentration of caffeine. The hypothesis was supported because a significant decrease of the total number of cells when caffeine solution was added to the experimental group was clearly shown. An addition of small amounts of caffeine does inhibit cell proliferation and affect cell viability during the lab experimentation one more
