Distilled water

wasn’t as hard as the day before. These days’ data was a hypotonic solution because there was no met movement of water, therefore the egg enlarged. On day two we recorded the data, then we poured the vinegar out of the cup and added distilled water in, to leave overnight. We predicted the egg would get softer, bigger and bouncier than before. Our independent variable was the distilled water and dependent variable was our egg. We thought the egg would get bigger through deductive reasoning…

project were general protective personal equipment such as lab coat, gloves and googles, 125 milliliter Erlenmeyer flask, 50 milliliter burette, 50 milliliter beaker, graduated cylinder, scale, vitamin c, phenolphthalein, methyl orange, deionized water and the following chemicals: sodium hydroxide, potassium hydrogen phthalate, hydrochloric acid and sodium bicarbonate. When it comes to these chemicals, make sure to wear the general protective personal equipment and handle with caution because…

9/24/2015 Steps and Procedures 1. Blend a 120 g sample of each fruit separately a in a blender with about 50 mL of distilled water. Strain any extra pulp with a cheesecloth. You should have at least around 120 ml of substance. 2. Separate each of the liquids into half and put each half into its own separate individual beakers .So you should have 8 beaker with 100ml of each…

source was ESI+ (electrospray ionisation). The solvents Eluent A2 (100 mL eluent A 213 concentrate [6-aminoquinolyl-N-hydroxysuccinimidyl carbamate + acetonitrile] and 900 mL 214 distilled water) and Eluent B (acetonitrile) were used. The MS analysis was done using a Waters 215 ACQUITY Tandem Triple Quadrupole Spectrometer (Waters Corporation, Massachusetts, USA) 216 with capillary voltage set at 3.5 kV and 15 V for cone voltage. The source and desolvation 217 temperatures were set at 120 and…

individually massed and the percentage-by-mass could be determined. The best way to get the sand and shells by themselves is to get rid of the salt. Since salt is dissolvable in water, you use water solubility (Hallows, 2014). Water solubility is defined as a substance being able to completely dissolve in water (“Water Soluble”). So setting up the filtration and having salt completely gone was a physical change (Hallows, 2014). The next two components that are left are sand and the shells. Sand…

made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is performed correctly, the actual density of water will equal the theoretical density of water. In the second section, the density of an aluminum sample will be measured and afterwards compared to the accepted density of aluminum and an unknown sample…

Create a table consisting of four columns that features: time intervals of 30 seconds, number of bubbles that have risen in the warm sugar water yeast mixture, number of bubbles that have risen in the cold sugar water yeast mixture, and the number of bubbles that have risen in the distilled warm water yeast mixture. Fill the given plastic container with warm water halfway. Place a thermometer in the plastic container, and record temperature. Acquire scale, position wax paper over platform, and…

Materials. Numerous substances in the experiment were used. The most frequently used was the unknown due to the need to test its physical and chemical qualities. When a solution of the unknown was made, 1.000 g of the unknown and 1.0 mL of water was used to make it. To test for the possible ions, 1.0 mL of silver nitrate and 1.0 mL of nitric acid were used for the ion test. Ammonium chloride and calcium chloride were the two compounds that were tested on to see if either were the unknown…

from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The input is carbon dioxide (CO2), water (H2O), minerals and light, and the output is carbohydrates (food) that we need for our nourishment Chads are circles cut out of leafs. 1g of baking soda is mixed in with 100ml of water. The chads are placed into a…

Adding distilled water to this mixture will eradicate any traces of salt (sodium ethanoate and sodium sulfate) and remaining soluble impurities when it is discarded (AUS-e-TUTE. 2015.) Any remaining traces of ethanoic acid and sulfuric acid is neutralised by sodium carbonate (as shown in equation 1) (Fischer esterification reaction), which is converted to soluble sodium sulfate, sodium ethanoate and carbon dioxide which is released by inverting the separating funnel, and opening the tap.…
