The independent variable of this experiment is the amount used of each substance. However, these were not not be varied. The dependent variable is the amount of hydrogen gas which is formed. The controlled variables are the pressure and temperature in the room, and the width (and thereby weight) of the magnesium ribbon.
Materials used:Magnesium (Mg) ribbonHydrochloric acid (HCl), 35% concentratedCopper (Cu) wireEudiometerThermometerBarometerMeasuring cylinder (2000 cm3)Method:50 mm of the Mg ribbon was weighed.10 cm3 of HCl was poured into the eudiometer.The rest of the eudiometer was filled with water.The Mg ribbon was wrapped around the Cu wire and hung in the eudiometer cork.The measuring cylinder was filled with water.The eudiometer was put upside-down in the measuring cylinder.After the reaction between HCl and Mg was complete, the eudiometer was allowed to cool down to reach room temperature.The eudiometer was arranged so that the gas inside had the same pressure as the air pressure outside the room.The molar mass of magnesium was calculated usingIn order to ensure that the investigation resulted in valid results, the experiment was conducted four times.These were the measured values:Table 1: Controlled VariablesVariable ValuePressure of the room 100.3 * 103 PaTemperature of the room 292.65 K

The experiments are presented in Table Table 1.In order to facilitate the verification of a valid test for the validity of the findings, the experimentors used the following methods:1) Electromagnetic field analysis (EM) spectroscopy (EIA) were performed at 0.01 mm for 40 and 40 kHz.Electromagnetic field analysis (EM-EIA) was conducted at 1.1 × 108 N(HCl).EIA is used to determine the electrical activity in the walls of a building using radio-frequency waves, which are the waves that are generated and passed through a building’s walls, by placing an anvil in the wall of the building. The EM energy is used to calculate the number of units of energy used in the electrical charge. This information is used to determine the current to the walls of the building by the application of the new power. The current is applied to the electrical elements in the building which are active for a period of one hour.The electric current generated through a wall of the building is expressed as the electrical charge of a piece of metal when the wall is fully open. This is shown by the number of units of charge multiplied by the number of electrons contained within the piece of metal. The values are denoted as 0.00015, 0.015, 0.00015 and 0.015 units.The measurement is performed under the influence of a lamp. The luminous white screen is placed between wires and placed on the floor of the living room (inside the building). Light is emitted in a beam by a bulb within the room. The lighting in the room is placed on a white screen with the bulb on it. There is no need to use a special lighting system until the lamp is still open and running.The EIA method is used when the walls of a building are illuminated by lamps, which are not allowed to go off. In cases of electrical shock, the lights are switched off. In this manner, while standing and doing work, many of the electrical elements in the building are constantly working. To avoid such a situation, EIA was used for both the temperature of the room and ambient temperature. The ambient temperature in a room is calculated by calculating the temperature difference between the room’s humidity and absolute humidity. The difference is taken into account in the experiments. For non-normal conditions, EIA is used by placing a light source through the ceiling.The ambient temperature of the room is calculated automatically at 10 and 40 Hz within 5 minutes after the light is placed and 5 and 10 minutes after the heat is taken out. The temperature difference becomes significant after the heat and the ambient temperature has decreased, and the effect becomes more pronounced within 5 minutes after the light is placed.The EIA procedure was not modified using any other method when the EIA was used.This method provides a number of advantages to the user and increases the number of experiments. An additional advantage is that it can ensure that all the measurements are made by hand without the need of special equipment. The EIA system can be modified by simply applying a different set of measurements, including the measurements in einsteinometers and radio-electric field spectroscopes (RIC spectroscopes) which are only used when the EIA procedure is not yet perfect. For example, the EIA procedure using R IC.I.I.I.I.C-6A may be used for measurement of the energy level within the building. The EIA procedure can be used for measurements of the electrical conductivity of the building (e.g., temperature and distance inside the building). The EIA procedure also requires that all the measurements be done through an antenna.
