Independent Variable for magnesium oxide lab

burning magnesium ribbon lab report

It had a shiny and glossy silver lustre with a smooth clean surface, no longer feeling waxy. The independent variable in a science experiment is the variablethat you change on purpose. A compound is a material in which atoms of different elements are bonded to one another. Hypothesis Part A- It is believed that it would be Synthesis reaction. Therefore in the finding of. There are two types of variables-independent and dependent. It burns in air with a brilliant white light, as seen in the experiment, and for this reason is often used in flares and fireworks.

Then I took Magnesium and put it in the first one. It had a hazy, dark metallic sheen to its appearance. A magnesium-poor product would have a ratio of Mg-to-O that is less than the 1-to-1 expected. Your independent variable would be the stress and the dependent variable would be the heart rate. A mole of an element is the mass in grams that is numerically equal to the atomic weight.

Personal Reflections We found this experiment to be interesting and surprising even though it was quick and relatively easy. Purpose- The overall purpose of the lab is to identify chemical and physical changes. The change in mass when magnesium burns Class practical Magnesium is weighed and then heated in a crucible. The magnesium oxide seemed like white ash in color. General Instructions A Place to Start : 1.

The flame was removed and to cool the crucible with lid. I Stated that Water, Oxygen, Hydrogen, and Carbon would be produced. An observation is a fact obtained with the senses. It is something thatdepends on other factors. Once the reaction starts, more than enough heat is made by the reaction to continue to give activation energy to other reactants.

After the magnesium ribbon is heated and when magnesium oxide is formed, measure the weight and compare the weight of magnesium with magnesium oxide. This ultimately created a dose­response experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. Do not inhale the magnesium ribbon. The expected product is MgO, so the 1-to-1 mole ratio Mg to O in the product is all that is required. The law of definite proportions states that a specific compound always contains the same amount of elements in fixed proportions by mass.

It is also required to be cautious when working with the acids used in this lab because they can cause burning and irritation of the skin. Magnesium burns in air to form Magnesium oxide MgO. When they are combined they form magnesium chloride and Hydrogen gas. In this investigation, a wide range of concentrations of Sodium Chloride NaCl solution were created and the effects that they had on radish seeds were tested. Even the thermite reaction, which is so exothermic that the iron produced is red hot and molten, requires a lot of heat to get it going. The dependent variable relies on the change of the independent variable to change itself. Partially covered the crucible with the cover and heated it using a Bunsen burner until the magnesium ignited.

What is burning of magnesium ribbon : exothermic or endothermic?

burning magnesium ribbon lab report

Bring a small piece of magnesium ribbon. Magnesium gives up two electrons to oxygen atoms to form this powdery product. For example, in a sample of a made up compound of oxygen and lead, one mole of lead has a molar mass of 207. Write the balanced equation for the combustion of acetylene. Becuase if the temperature changes you can notice it better this way.

In order to activate the reaction of Magnesium, a source of energy was needed. If it is looking tarnished or black then clean it using the emery paper. Data Collection: Table 1 Mass of empty crucible, crucible + Mg roughly 1cm pieces of a 15-cm piece of magnesium ribbon , and crucible +MgxOy. Hold the tip of the ribbon next to the flame of the burner. This creates a pattern of endlessly repeating lattice of ions they do not exist as a free unit of atoms but in crystal lattices with repeating ions in specific ratios which is why empirical formula is used as a form of identification for defining an ionic-bonded substance.

Oxygen and magnesium combine in a chemical reaction to form this compound. Chemical reaction, Chemistry, Chlorine 1071 Words 5 Pages The Enthalpy of Formation of Magnesium Carbonate By: Jessica Miller T. The flame provided a source of heat which prompted a chemical reaction to proceed. A calcium carbide granule is dropped in the water in the container and bubbles of acetylene gas begin to be produced. Make sure that everyone in your group understands the process and purpose before you get started. The pipe clay triangle was placed over the tripod, ensuring that it is secure.
