Review of the Related Literature Cucumber The cucumber (Cucumis sativus) is a widely cultivated plant in the gourd family Cucurbitaceae‚ which includes squash‚ and in the same genus as the muskmelon. The plant is a creeping vine which bears cylindrical edible fruit when ripe. There are three main varieties of cucumber: "slicing"‚ "pickling"‚ and "burpless". Within these varieties‚ several different cultivars have emerged. The cucumber is originally from India‚ but is now grown on most continents

My hypothesis is that the eggs will absorb the contents it’s placed in and will become heavier. First‚ the fresh hen’s eggs were placed in vinegar. On March 10th‚ 12 eggs were placed

The shell project Our teacher gave the class a project that was about shells and burning them with vinegar. All of us started to put the shells in the vinegar in Tuesday. Then we waited till Thursday the 3rd shell in my teams cup was already dissolving. After seeing on what happened to the shells being in the vinegar for a few days me and my team worked on the weight the shells were. We did graphs‚ charts a lot of work and so little time‚ but we kinda almost completed it‚ I mean one of my

an Alka-Seltzer tablet in different measures of an acidic solution (Vinegar). Through understanding of stoichiometric relationships and limiting reactants‚ quantities of substances yielded or consumed in a reaction can be determined by analyzing the amount of material involved. A vinegar-water solution is employed in this experiment because a fixed amount of NaCO3 can be reacted in pure water‚ by manipulating the amount of vinegar in the dissolving solution‚ the amount of acid capable of reacting

Amanda Anile Course: CHM 101 (E05N)-NVCC Professor: Mihaela Chamberlin Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic solution
