red indicator was added to PVA solution for the cross-linking part. 0.4 grams of borax was dissolved into 10 mL of hot water. 3.0 mL of the dissolved borax was added to the cooled PVA solution in 1.0 mL aliquots. The cross-linking consisted of the addition of sulfuric acid and sodium hydroxide. 3.0 M H2SO4 was added to the mixture until it became faint red. 2.0 mL of 1.0 M NaOH was added to the mixture to neutralize the H2SO4. Originally‚ it was planned to measure viscosity quantitatively with a start

3-dibromo-3-phenylpropanoic was found to determine syn or anti addition of bromines. The melting point was 199-203°C and the NMR J values angle is at 167 which both prove the erythro-2‚3-dibromo-3-phenylpropanoic. Determination of the Stereochemistry of 2‚3-dibromo-3-phenylpropanoic acid. Introduction The purpose of this experiment was to determine the mechanism of the reaction of trans-cinnamic acid with the addition of bromines to 2‚3-dibromo-3-phenylpropanoic acid. An addition of bromine was added to trans-cinnamic

being a science‚ is simply just a creation invented for the present times. We‚ as humans‚ learn regular arithmetic as children‚ with games such as marbles and other fun counting games. Eventually‚ as we get to elementary school‚ we learn the use of addition‚ subtraction‚ division‚ and multiplication‚ the basics essentially. Math tends become more complex as we move on to middle school and high school. Middle school and high school is where we eventually start using higher arithmetic to understand the
