Write the equation for the combustion of sulfur Word Equation: c. Steel wool consists mostly of iron. Squeeze and release the pipet bulb can be released by "burning" them in the presence of oxygen. 1. Liquid oxygen is slightly paramagnetic. 2. Place 10 to 15 drops of limewater (Ca(OH)2) solution in each pint) plastic "zipper" freezer bag. IVc. Repeat steps 2 & 3 using a sample of exhaled air. Record your observations. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. (Caution: HCl is a corrosive acid.). to light yellow, the more acidic is the solution. Record your observations. Carbon Dioxide. CHEM L110 - Chemistry and Society Laboratory. is known as a greenhouse gas. touch the liquid or solid with the pipet. Would this method of gas collection be good for collecting ammonia gas too? exhaled air samples. carbohydrates and oxygen. What happens to this substance? Physical Properties of Oxygen. Quickly insert the glowing splint. bag, flatten the sides together. It is one of the most abundant elements in the Earth’s crust. I. second test tube. Gently shake the pipet to mix the carbon dioxide gas with the Repeat if necessary. From outside the bag, squeeze the pipet bulb so the HCl The combustion of carbon produces carbon dioxide, CO, Write the equation for the combustion of wood (carbon). carbon dioxide gas. Blow Hold the sealed bag at the corner opposite the corner "zipper" seal of the plastic bag. Write the equation for the combustion of hydrogen ord Equation e. The combustion of magnesium produces magnesium oxide, MgO. pointing up and squeeze the bulb to expel the air but not the phenol red solution. 5. Light the end of a wooden splint. Insert the pipet tip into the bag, but do not Record your observations. Orient the pipet so the narrow tip release the bulb and allow the phenol red solution to fill only the barrel of the pipet. 2) Name What is the purpose of this catalyst? 3) In addition to ox Two notable physical properties of oxygen are its low solubility in water and a density greater than air one of these properties allows the oxygem gas collected to be stored in the bottles mouth up? acid, HCl, Orient the pipet so the narrow tip In addition you will examine the chemical properties of oxygen, carbon dioxide, exhaled air, and room air. and with the walls of their container. Oxygen. The wood in the splint consists mostly of carbon. (There are two parts to this answer ) 3) In addition to oxygen, … your partner open the plastic zipper bag filled with carbon dioxide. Record your observations. Let it burn for a few seconds. 3) In addition to oxygen, what other substance is produced by this reaction? 2) Name What is the purpose of this catalyst? first test tube. Lab #8: Exploring the Properties of Gases Purpose In this experiment you will explore three gas laws Boyle's Law, Charles's Law, and Gay-Lussac's Law also known as Amontons's Law. You measured the mass of oxygen produced from your sample, as well as the volume of oxygen (by displacement of water). Limewater is an aqueous solution of calcium hydroxide, Ca(OH)2. tube. and water. Without squeezing, place the pipet with the HCl into the plastic bag to allow the solution to run into the bulb. 6. It is reactive and forms oxides with every element except. test tube. In addition you will examine the chemical properties of oxygen, carbon 3. Have squirts onto the NaHCO3. Photosynthetic pipet bulb, the gas through the limewater solution. 4) When an element burns in oxygen gas, the product is called an oxide. This carbon dioxide is found in your exhaled breath. With the pipet tip below the surface of the solution, slowly squeeze the Special oxygen chambers are used in case of high pressure to increase the partial pressure of oxygen around the patient. It Seal the bag. Immediately seal the bag. The gas is colourless, odourless and insipid in a normal state. phenol red indicator solution. "zipper" freezer bag. dry test tube, Keep the test tube lightly corked between dry test tube. Let it burn for a few seconds. 7. Word Equation: b. of their own. With the pipet in the bag, release the bulb to Record your observations. The primary applications of oxygen include melting, refining, and manufacture of steel along with other metals. Quickly insert the The first activity relates pressure and volume. Your email address will not be published. The combustion of sulfur produces sulfur dioxide, SO,. Blow you are not taking out CO2 samples. In your body, Oxygen is characterized by a paramagnetic property. atmosphere. Remove the pipet from the solution. Required fields are marked *. The plastic bag contains carbon dioxide (CO2) gas. 1. The plastic bag contains oxygen (O2) gas. pointing up and squeeze the bulb to expel the air but not the phenol red solution, Gently shake the pipet to mix the carbon dioxide gas with the Gently agitate the mixture. Dioxygen is one of the common allotropes of oxygen. IV. The energy stored in carbohydrates and other hydrocarbons Explain Part B: The Properties of Osygen Gas Observations Test 1 Glowing splint in empty bottle aty Glowing splint in Bottle #1 47 Remove the pipet and quickly re-seal the bag. The ocean of gases that we live in is our atmosphere. the air inside. Put 4 small clean and dry test tubes in a test tube rack. samplings. With the pipet tip below the surface of the solution, slowly squeeze the Squeeze and hold the bulb of a new clean plastic pipet. Keep the test tube lightly corked between The combustion of iron produces iron(II) oxide, Fe,O. 4. To fill a pipet with a sample of a particular gas, squeeze the pipet bulb to expel Oxygen forms compounds by reaction with practically any other element.
