Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate

purpose of this experiment is to use Volumetric Analysis to determine the concentration of acetic acid in white vinegar. 2.0 Theory The concentration is a measurement of relative amounts of solute and solvent. There are many diverse ways of expressing concentration but the most accepted and widely used is molar concentration and regularly referred to as molarity which is defined in mole‚ the amount of solute dissolved in one litre of solution. [pic] In this experiment there are solutions

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation‚ Calcium + Hydrochloric Calcium + Carbon

Some metals react with acids while others do not. In this experiment‚ students will perform 2 reactions: aluminum/zinc with excess 6M hydrochloric acid and aluminum-zinc alloy with excess 6M hydrochloric acid. The purpose of this experiment is to determine the atomic mass of each metal and the percent composition of a known mass aluminum-zinc alloy by determining the moles of H2 gas formed. Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) 1 mole of H2(g) is produced for every 1 mole of Zn(s) 2. 2Al(s)

react with hydrochloric acid; and 1 cm3 of element X has a mass of 1.8 grams. Is element X a metal or non-metal? Give the reasons for your answer. Element X is most likely a typical non-metal. First of all‚ element X melts in boiling water; non-metals typically have low melting and boiling points. Furthermore‚ element X is unable to react with hydrochloric acid. This greatly indicates that element X is a non-metal as most non-metals fail to react with hydrochloric or dilute acids. In order

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due

Diffusion of Hydrochloric Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar will
