Determining the value of molar mass of chosen compound Marta Dürrigl 1mmA Chemical reaction: b.) CaCO3 (s) + 2HCl (aq) ----------- CaCl2 (aq) + CO2 (g) + H2O(l) AIM: The aim of this investigation is to experimentally determine the molar mass of carbon dioxide (CO2) by measuring its volume and calculating its mass. CO2 which we will measure will arise as a product of a chemical reaction between Calcium Carbonate (CaCO3) and Hydrochloric acid (HCl) as it is shown in the chemical

study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine

Stoichiometry lab By: James Stewart Purpose: To calculate mole ratios Introduction: There are two types of chemical analysis; qualitative analysis which is the identification of a substance present in a material‚ and qualitative analysis which measures the amount of the substance. In this lab‚ you will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation

Hess’s Law and the Molar Enthalpy of Combustion for Magnesium Purpose: The purpose of the lab ultimately is to find the molar enthalpy of magnesium. This is done by finding the enthalpy changes of reactions (2) and (3). The enthalpy changes of reactions (2) and (3) along with the enthalpy change given for reaction (4) can be used to arrive at a value of the molar enthalpy of combustion of magnesium by using Hess’s Law. Hypothesis: By using Hess’s law to calculate the molar enthalpy of combustion

Understanding technology is important when managing companies that have computer technology as their backbone. Knowing this information helps the employees responsible for information management to make informed choices about how to implement technology. These decisions allow the manager to successfully use time and resources in apparently menacing tasks. This is shown in the two scenarios. In the first scenario‚ a marketing assistant of a consumer electronics company is given the task of maintain
