Marble Chips Experiment Pilot Aim: To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. Prediction: I predict that the more hydrochloric acid there is the faster the chemical reaction. I also predict that the more dilute the acid is (the more water there is with the acid) the slower the chemical reaction. Hypothesis: I predicted what I did because the more concentrated the hydrochloric acid is the more energy there will be and

Experiment to Find the Reaction of Potato Chips in a Salt Solution Aim: to find a reaction of potato chips in a salt solution. Hypothesis: I predict that the potato will change in mass. The difference will occur in accordance to the difference of concentration of the salt solution each potato chip is submerged in. The cause of this change in mass is called osmosis. Osmosis is the movement of water through cells in plants. I make my prediction on the pretext that water diffuses from

Does temperature affect how wide a chocolate chip cookie gets? If temperature affects how a chocolate chip cookie is baked, then temperature will affect how wide the cookie grows in width. The procedures for the experiment were; Warm up the oven to the desired temperatures. Prepare the chocolate chip cookie dough into about 3 sections of 28 grams, while the oven is heating up. Place the cookie dough onto the pan and put into the oven once the oven is heated up. Leave the cookies in the oven to cook
Observations and Explanation: When the hydrochloric acid was poured into marble chips, gas bubbles were seen – signifying the carbon dioxide (gas) that was being produced due to the chemical reaction. As the reaction was taking place, the water in the measuring cylinder was being displaced – indicating that the calcium carbonate (in the form of marble chips) was displacing the hydrogen in the hydrochloric acid. Discussion: According to the results shown, 2 M hydrochloric acid that was more concentrated

Amount Of Solution = 10ml Personal Information ==================== P6 a I) In our experiment to study Osmosis I think that the 0.6 M solution will give the chip a rubbery effect because in the 0.6 M solution the
by a simple experiment, described in Supplemental Material: Klarite chips of the batch 2009 and of the batch 2012 were separately dipped in EtOH in new (unused) weighing glasses and the Raman spectra measured without cover (i.e. undefined thickness and evaporation of EtOH during the experiment). No Teflon cell, no tubings, no re-using of solvent or chips. Development of the BPE Raman bands was noted only in the case of the batch 2009. Please note, that without having the Klarite chips of the batch
Investigate the Effect of Varying Solution Concentration on Osmosis in a Potato Chip Prediction A definition of osmosis is: 'the movement of water molecules from an area of high water concentration to a low water concentration across a semi-permeable membrane' (Oxforddictionary 2000). In a high concentration of water the amount of solute (e.g. sugar) is low. These solutions are usually known as a dilute or weak solution. But in a low concentration of water the amount of solute (e.g. sugar) is
illustrative paper. I will conclude this paper with a reflection of this experience. When I first learned about this experimentation, I looked into intervention programs for people with hearing disabilities in Montréal. The first one I researched was CHIP [Communicaid for Hearing Impaired Persons]. It is a non-profit organization that has a mission towards helping people with hearing impairment. They promote programs similar to HEAR [Hearing Education for Aural Rehabilitation] to help teach people with
How the change of Hydrochloric Acid concentration affects the rate of reaction with Marble Chips Aim To find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid. With the equation CaCO3 + 2HCl CaCl2 +H2O + CO2. The rate of the reaction affects how quickly the CO2 is produced. Background Knowledge ==================== The rate of reaction depends on how often and how hard the reacting particles collide with each
Osmosis of a Turnip and a Potato Chip The problem: I have been asked to investigate why a turnip will taste sweeter than a potato chip. What I am actually been asked to investigate is the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Background Knowledge: Osmosis is a special type of diffusion involving the movement of water molecules through a partially permeable membrane and
in Potato Chips My aim is to investigate the amount of osmotic activity between a potato chip and different concentrations of sucrose. The following affect the rate of osmosis: Temperature The warmer most things are the more quickly particles move, therefore increased temperature will increase the rate of osmosis. So, if a potato chip is in a highly concentrated solution the water molecules will quickly leave the chip because of the increase in temperature or if the chip is in a high

Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips Introduction ============ There are many factors that will affect the rate of reaction between hydrochloric acid and calcium carbonate. Some of them are as follows: * Temperature - If the temperature is higher, then the molecules in the solution have more energy, causing them to move around more which would mean they would react faster. * The surface area of the calcium
Investigation of the reaction between hydrochloric acid and marble chips A chemical reaction is when two or more substance called reactants are chemically bonded to form a new product, as a result of the process, for a reaction to take place, the particles must have enough kinetic energy to collide and form new bonds , this is called a successful collision. The minimum amount of energy needed for a successful collision is activation energy, which is “The energy that an atomic system must acquire
