Hydrochloric acid

In this today’s lab, Percent Yield of Hydrogen Gas from Magnesium and Hydrochloric Acid, the purpose is to study the stoichiometry of H2 produced from the reaction between magnesium (Mg) and hydrochloric acid (HCl). The chemical equation for this reaction is Mg +2HCl -> MgCl2 + H2. It was predicted that 0.0029 moles of hydrogen gas would be formed from 0.07g of magnesium metal and 10 mL of hydrochloric acid. The hypothesis was proven correct based on an actual yield of 0.00299 moles of hydrogen gas

In this lab, we balanced the equation xZn(s) + yHCl(aq) → ZnxCly (s) + y/2H2(g) by the information obtained from the lab. When zinc and hydrochloric acid are mixed together, the reaction took place in an evaporating dish that was accompanied by hydrogen gas. Then we measured out the mass of zinc and chlorine in the reaction and calculated the empirical formula of zinc chloride which was ZnCl8. Based on the conservation of mass, we balanced the equation and got Zn(s) + 8 HCl (aq) → ZnCl8 (s) + 4 H2

through clicking “Sensor View” and changing the “Time Based” data and interval. The interval was changed to 15 seconds and the derived settings were saved. During part B of the experiment, the reaction of Hydrochloric Acid and Ammonium hydroxide were conducted. During reaction 1, Hydrochloric acid was combined with Ammonium Hydroxide. To do this, two Styrofoam cups were stacked together and placed into a beaker. 50 ml of the “2 M HCL” solution prepared in step 1 was added to the Styrofoam cup. The

(stomach acid) to produce CO₂ gas to test your engineering design. The reaction of hydrochloric acid and sodium bicarbonate is: HCL + NaHCO₃, one mole of CO₂ gas is produced. Regarding the other products, NaCl dissolves in the water to create a salt solution which occupies only a small portion of the volume inside the bag. Pre-Lab: Grab a one quart zip-lock®

Partners: Robert LOWSLEY-WILLIAMS Magnesium and Hydrochloric acid 1. INTRODUCTION I have been asked to do an experiment on the rates of reactions experiment to see the rates of reactions and come up with a conclusion to why it happens, I will also have one variable which me and Robert have chosen to be the temperatures, we will have the temperatures: 15 °C 30 °C 40 °C 50 °C 60 °C With these results we will compare the results we got from different temperatures to see if there is any particular

Reaction Between Hydrochloric Acid and Magnesium Introduction In the reaction between hydrochloric acid and magnesium, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas. All chemical reactions involve reactants which when mixed may cause a chemical reaction which will make products. In my case the reactants are hydrochloric acid and magnesium ribbon

Title: The Effect Temperature of Sodium Thiosulfate Has On The Rate of Reaction with Hydrochloric Acid Statement of Inquiry: What is the effect of changing a factor on the rate of chemical reaction? Aim: The aim of this experiment is to observe how by increasing the temperature of sodium thiosulfate in a solution with 2.0 molar Hydrochloric acid can affect the rate of reaction and the rate in which a precipitate is formed. Hypothesis: If the temperature of the sodium thiosulfate is increased

Using the syringe method I am going to investigate the reaction between Marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed. Chemistry Using the syringe method I am going to investigate the reaction between Marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed. This reaction rate will tell me how fast or slow a chemical reaction is and there are four things that could affect this greatly they are- * Concentration-An increase

Aim: To investigate how concentration affects the volume of gas that is produced after one minute. Background Information: In this experiment hydrochloric acid is reacting with magnesium to form magnesium chloride and hydrogen, and the chemical equation goes as follows: Mg(s) + 2HCl(aq) ==> MgCl2 (aq) + H2 (g) Particles must collide with each other at a certain activation energy in order for a chemical reaction to take place. Reducing the concentration reduces the amount of particles, which

To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips, which I will vary the sizes as powder, small chips and large chips. I will also be changing the concentration, the different concentrations are as follows 0.2m, 0.5m, 1m, 1.5, 2m. I have chosen these concentrations as they
