The three reactions used in this experiment are: (1) NaOH(s) Na+(aq) + OH-(aq) (2) NaOH(s) + H+(aq) + Cl-(aq) H2O(l) + Na+(aq) + Cl-(aq) (3) Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) H2O(l) + Na+(aq) + Cl-(aq) In

The Infrared spectra confirmed ester peaks: two C-O peaks at 1045cm-1 and 1241cm-1 and C=O at 1746cm-1 . Introduction: In this experiment‚ acetic acid and n-octanol will be used to prepare an ester‚ octyl acetate‚ by process of esterification. In addition to octyl acetate‚ possible side products include: water‚ unreacted octanol

Kyle Sy Ting‚ Shermae Tomimbang‚ Charisse Christine I. Introduction Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare‚ meaning "to glue." This occurs in biology in three main examples: 1. The clumping of cells such as bacteria or red blood cells in the presence of an antibody. The antibody or other molecule binds multiple particles and joins them‚ creating a large complex. 2. The coalescing of small particles that are suspended in

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average

They ranged from ancient Greek/Roman statues‚ Indian carvings‚ Egyptian mummies‚ to even Central American relics which we haven’t learned about in class. The piece that stood out to me the most‚ and what I will focus on for the rest of this essay‚ is the Aphrodite (Venus) statue‚ which is a Roman copy of the Greek original from the 1st century CE. Upon arriving at the Carlos Museum‚ Aphrodite (Venus) is one of the first works you immediately see to the right of the Museum’s foyer. Featured

consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released. Mass of carbon dioxide = m2 - m1 Equation 1 was used as an experimental procedure created to help find out the amount of carbon dioxide. To find how much water was released can be seen in Equation 2. Mass of water= m2 - m1 Like Equation 1‚ Equation 2 was also created to help find the amount of water released. To find the m2 in Equation 1 and Equation 2 it can be found as seen in Equation 3. m2=

Input control There are different actions needed before the execution of the marketing plan. Financially‚ more funds are needed for advertising MIXY to increase awareness‚ new product development‚ and better colors for the packaging. MIXY is not advertised and it needs to be in a larger product line to compete better. Also‚ as the packaging is made by the same supplier as CL‚ it should differ to be easily recognized. More expenditure is also needed for the R&D as the company is strong in
