Gas grills

The purpose of using a lit match to start the fire in a gas grill is... 

Place the skillet directly on the coals or on the grill of a gas grill and heat it until it s literally white hot. 

One disadvantage of burning propane (CjHg) is that carbon dioxide (CO2) is one of the products. The released carbon dioxide increases the growing concentration of CO2 in the atmosphere. How many moles of carbon dioxide are produced when 10.0 moles of propane are burned in excess oxygen in a gas grill ... 

From barbecuing on a gas grill to taking a ride in a hot-air balloon, many activities involve gases. It is important to be able to predict what effect changes in pressure, temperature, volume, or amount, will have on the properties and behavior of a gas.

These short hydrocarbon chains have low boiling points, so they evaporate and burn easily. That makes methane a good fuel for your stove or furnace. Propane is used in gas grills, lanterns, and to heat air in hot-air balloons. Butane often is used as a fuel for camp stoves and lighters. Longer hydrocarbons are found in oils and waxes. Carbon can form long chains that contain hundreds or even thousands of carbon atoms. These extremely long chains make up many of the plastics that you use. 

The structures of methane (left) and propane (right) are shown here. Count the number of carbon atoms in each. Many hydrocarbons are used for fuel. Methane is the main component in natural gas, and propane is used in gas grills. 

If you cook food using a gas grill, propane gas (CjHg) is burning in oxygen gas to produce carbon dioxide gas and steam. 

Draw the electron dot structure of propane, C3H8, the hydrocarbon fuel often used in gas grills. Describe the shape of the molecule. 

Propane, C3Hg, is a fuel commonly used for cooking on gas grills and for heating in rural areas where natural gas is unavailable. Propane reacts with oxygen gas to produce heat and the products carbon dioxide and water. This combustion reaction is represented by the unbalanced equation... 

Gas Grills Using outdoor grills is a popular way to cook. Gas grills burn either natural gas or propane that is mixed with air. The initial spark is provided by a grill starter. Propane is more commonly used for fuel because it can be supplied in liquid form in a portable tank. Combustion of liquid propane also releases more energy than natural gas. 

Real-World Reading Link Have you ever used a Bunsen burner or an outdoor gas grill If so, you have used an alkane. Natural gas and propane are the two most common gases used in these applications, and both are alkanes. 

Your family may have a "gas grill" for outdoor cooking. Gas grills typically use bottled propane gas (CsHs), which burns in air (oxygen) to produce carbon dioxide gas and water vapor. Write the unbalanced chemical equation for this process. Gas grills should never be used indoors, however, because if the supply of oxygen is restricted, the products of the reaction tend to be water vapor and toxic carbon monoxide, instead of nontoxic carbon dioxide. Write the unbalanced chemical equation for this process.

Which of the following would you characterize as a pure or nearly pure substance (a) baking powder (b) lemon juice (c) propane gas, used in outdoor gas grills (d) aluminum foil (e) ibuprofen (f) bourbon whiskey (g) helium gas (h) clear water pumped from a deep aquifer. 

Propane belongs to a class of compounds called hydrocarbons, compounds composed only of carbon and hydrogen. The product of this reaction is heat. You don t burn propane in your gas grill to add carbon dioxide to the atmosphere — you want the heat for cooking your steaks. 

Straight-chained alkanes and some cycloalkanes are primarily used as fuels. Methane is the primary component in natural gas and, like most hydrocarbons, is odorless. The gas companies add a stinky organic compound containing sulfur, called a mercaptan, to the natural gas to help alert you to gas leaks. Butane is used in lighters, and propane is used in gas grills. Some of the heavier hydrocarbons are found in petroleum. Combustion is the primary reaction of alkanes. 

Consider the combustion of propane (CsHg). Commonly used as fuel in gas grills, propane (a gas) combines with oxygen (O2, a gas) to form carbon dioxide (CO2, a gas) and water (H2O, a liquid). Because each propane molecule contains three carbon atoms and because carbon dioxide (with one carbon atom) is the only product that contains carbon, each propane molecule that reacts must produce three CO2 molecules. Similarly, the eight hydrogen atoms from each propane molecule should produce four water molecules. These data give ten oxygen atoms in the products (from three CO2 and four H2O molecules), so there must be five O2 molecules in the reactants. Thus, the chemical equation for this reaction is...
