reaction would be higher. Those factors would affect the speed and the amount the atoms are moving at therefore effecting the amount that the particles collide and hence impacting the rate of reaction. The two reactants involved in the experiment are Sodium Thiosulfate

Objective: I will be combining calcium carbonate with hydrochloric acid as a case study to measure the rate of chemical reaction. This gives us the equation CaCO3 + 2HCl  H2O + CaCl2 + CO2 Background Information: Several factors are already known which increase (or decrease) the rate of reaction. An increase in concentration of the acid allows for a greater number of hydrochloric acid molecules colliding into those of calcium carbonate. Although not every single particle would result in a successful

Procedures 1.First thing needed is a plastic bag open the plastic bag and take about a teaspoon of calcium chloride, put the calcium chloride in one corner of the bag. Then take about a half teaspoon of sodium bicarbonate and put it in the opposite corner of the bag. Then lay the bag flat on the table use about 5 mL of phenol red. Once the phenol red is in quickly lift your bag and put all the substances in one corner. Then observe 2.Reference procedure one for first step.Lay bag down and add about

Nonosmotic Sodium Accumulation and Salt Sensitive hypertension As we discussed earlier, high sodium diet causes water retention and increases the blood pressure by increasing extracellular fluid volume. In contrast to this traditional view, Heer et al. 2000 performed an experiment in which they showed that consumption of high dietary sodium causes a relative shift of fluid from interstitial compartment to intravascular space. They selected 32 healthy male subjects and provided them with a diet rich

Conclusion: In Station 1- reaction 2, Station 3- reaction 1, Station 4-reaction 1, Station 5 reaction 1, Station 6-reaction 1 and 2, and Station 7- 1 and 2 there was chemical reaction because all of those mixed ionic compounds created a precipitate. However some solutions did not become insoluble and produce precipitates such as: Station 1- BaCl2 (aq) + KNO3 (aq) , Station 2- KNO3(aq) + AgNO3(aq) and KNO3(aq) + CaSO4(aq), Station 3- Na2CO3(aq) + KNO3(aq) , Station 4- NaPO4(aq) + KNO3(aq)

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction:

In this lab, a total of 9 reactions were complete, mixing 3 powders and 3 liquids. The powders were baking powder, baking soda, cornstarch. The liquids were water, iodine solution, and acetic acid. Of these experiments, 5 were chemical reactions and 4 were only physical changes. Of the powders, baking powder was the most reactive because it chemically reacted with all 3 liquids. Baking soda and cornstarch both reacted with 1 out of the 3 liquids. Baking soda reacted with acetic acid. Cornstarch reacted

Introduction During this lab, students observed that not all substances dissolve at the same rate. Many factors involved including the independent and dependent variables affect how distinct substances dissolve. Overall, the chemical reaction, “the amount of reactant that changes the product in a given time”, played an important part in this experiment, when proven how a substance can change into another element by either emitting or absorbing energy. (Tro, 2018). Within the chemical reaction are

Factors affecting reaction rates (video) | Khan Academy (Khan Acadamey, n.d.) Research question: In the chemical reaction between 0.25m Sodium Thiosulfate solution and 1.0M of Hydrochloric solution, how will a variety of temperatures, between 10oC and 45oC the Sodium Thiosulfate solution, affect the time it takes for the chemical reaction to occur? Possible Hazard: Potential Risks: Control Measures: Hydrochloric Acid solution. -Potential skin

Throughout this lab, four metal and four different aqueous solutions were observed under a microscope, to determine what kind of reactions were produced. The main idea of this lab was to observe and write chemical equations for the different single replacement reactions. This purpose was accomplished, as all reactions in this experiment were single replacement reactions, that either produced a reaction or none at all. A single replacement reaction is when a single element switches and replaces another

CHEM 122 – General Chemistry I Laboratory Name: Evalyne Kogi Section DM1 Name of Partner: Negin Soleimani Spring 2017 Instructor: Prentice Date of submission: 3/20/17 Experiment #5: SYNTHESIS OF TRIS NICKLE (II) CHLORIDE Abstract: We found the limiting reactant by calculating the number of moles of Tris based on moles of HYD used (0.00260) and number of moles of Tris based of moles of En(0.0032). Because the number of moles of tris based on moles of HYD used resulted

PbI2(ppt) + 2KNO3(aq). In experiment ten, claer sodium hydroxide and blue copper (II) nitrate were the reactants. When the two reactants combined together in a test tube, the solution immediately became foggy and a precipitate formed at the bottom of the test tube. Also, a double replacement reaction occurred when the two reactants were combined because the sodium in sodium hydroxide and copper from copper (II) nitrate switched places: forming sodium nitrate and copper (II) hydroxide precipitate

Sodium carbonate Overflowed in the molds making it difficult to get out of molds Muffin top Little moist in bottom and middle of molds Very dry on top Some bubbles were made when placed into the water bath Bubbles could be heard popping when in water Took a little bit to disintegrate There were holes when hardening from bubbles Trial 2 crumbled to pieces Trial 4 and 5 were still wet and crumbled and the top came off on Trial 5 An exothermic reaction occurred therefore the water bath became

BEHAVIOURAL PARAMETERS: Morris water maze Morris water maze consists of a large circular pool (100 cm in diameter, 35 cm in height), filled to a depth of 30 cm with water. Water was made opaque with titanium dioxide. The pool was divided arbitrarily, into four equal quadrants [12]. A clear Plexiglas platform with a diameter of 11cm was submerged 1cm below the water level. The platform was placed near the centre of a quadrant and rats were released into the water from 1 of the 3 remaining quadrants

Recommended from the American College of Sport Science, adults need 150 minutes of exercise a week. We often eat too much for how little we move. If you are looking to lose weight you will need an average of 250 minute moderate-intensity, which only comes out to about 50 minutes a day for 5 days. Not bad, right? Now let's break it down. Lets look at your lifestyle. Do you work a desk job, or a job that is not physically demanding? If so, a sedentary person will only average 1,000-3,000 steps a day

Our topic is clean water and sanitation. The product is a tablet that turns any type of substance into clean substance. The water can be sea water, sewage water or any other dirty water. The tablet dissolves into the liquid and releases some of the chemicals to purify the water instantly. The filthiness in the substance will then sink to the bottom, where the other chemicals in the tablet will absorb all the dirt. In this way, the water is completely clean and fresh.

the action potential, which is essentially the flow of ions in and out of the neuron that differ from the normal flow, one must understand the relation of ions, especially sodium and potassium, with the neuron. Neurons are covered by membranes that regulate the inflow and outflow of chemicals, and certain chemicals, like sodium and potassium can only flow in and out via channels along the membrane. At rest, the membrane maintains a certain polarization between the inside and outside of the neuron

involves the transfer of anions. However, unlike a single-replacement reaction, a double-replacement reaction has two anions being intrechanged. An example of this type of reaction would be the combination of hydrochloric acid and sodium hydroxide to form water and sodium chloride: HCl + NaOH --> H2O +
