WebWe’re asked to give the answer to the nearest kilojoule per mole. So our final answer is minus 891 kilojoules per mole of methane. The minus sign means that, for each mole of methane combusted with oxygen, 891 kilojoules of energy is transferred to the surroundings. So the reaction of methane with oxygen under standard conditions is … WebPeriodic trends in properties such as atomic size and ionic size, ionization energy, electron affinity, and electronegativity illustrate the strong connection between the chemical properties and the reactivity of the elements and their positions in the periodic table. In this section, we explore that connection by focusing on two periodic properties that correlate …

Web13 Which statements about hydrogen fuel cells are correct? 1 The reaction between hydrogen and oxygen is endothermic. 2 The waste product in a hydrogen fuel cell is water. 3 A chemical reaction in the cell produces hydrogen which is used as the fuel. 4 A hydrogen fuel cell is used to generate electricity. A 1 and 2 B 1 and 3 C 2 and 4 D 3 and 4 Methane is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing … Meer weergeven Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest … Meer weergeven Methane is used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG). … Meer weergeven Methane was discovered and isolated by Alessandro Volta between 1776 and 1778 when studying marsh gas from Lake Maggiore. It is the major component of natural gas, … Meer weergeven Etymologically, the word methane is coined from the chemical suffix "-ane", which denotes substances belonging to the alkane family; and the word methyl, which is … Meer weergeven The primary chemical reactions of methane are combustion, steam reforming to syngas, and halogenation. In general, methane reactions are difficult to control. Selective … Meer weergeven Geological routes The two main routes for geological methane generation are (i) organic (thermally … Meer weergeven In November 1776, methane was first scientifically identified by Italian physicist Alessandro Volta in the marshes of Lake Maggiore Meer weergeven WebQuestion: Using the periodic table complete the activity. Methane (CH4) is a gas that is found in small quantities in Earth's atmosphere. Which type of bonds does methane have and why does one carbon atom bond with four hydrogen atoms?
