The coefficients in a balanced chemical equation provide the mole-to- mole stoichiometry among the reactants and products. The molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. Complete combustion of methane When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH₂(g) + O₂(g) →CO₂(g) + H₂O(g) This type of reaction is referred to as a complete combustion reaction. Review Constants Perio Part A What coefficients are needed to balance the equation for the complete combustion of methane? Enter the coefficients in the order CH4, O2, CO2, and H₂O, respectively. Express your answer as four integers, separated by commas (e.g., 1,2,3,4).

E-85 is an alternative fuel for automobiles and light trucks that consists of 85.0% (by volume) ethanol (C2H5OH), and 15.0% gasoline.  When ethanol burns completely it produces CO2 and H2O. The balanced equation for the burning of ethanol isC2​H5​OH+3O2​-->2CO2​+3H2​OThe density of ethanol is 0.790 g/mL.   How many moles of carbon dioxide are produced by the complete combustion of the quantity of ethanol in 8.00 gallons of E-85 fuel?      _mol CO2

Nitrogen (N2)and hydrogen (H2) react to form ammonia(NH3). Consider the mixture of N2 and H2 shown in theaccompanying diagram. The blue spheres represent N, andthe white ones represent H. (a) Write the balanced chemicalequation for the reaction. (b) What is the limiting reactant?(c) How many molecules of ammonia can be made, assumingthe reaction goes to completion, based on the diagram?(d) Are any reactant molecules left over, based on the diagram?If so, how many of which type are left over?

In a lab, a grade 11 chemistry student used 0.0123 mol of solid magnesium metal. The student proceeds to burn the magnesium metal in a Bunsen burned with an excess amount of oxygen gas to produce 0.41g of magnesium oxide based on the following balanced equation: 2Mg(s) + 02(g) —> 2MgO(s). The theoretical amount of magnesium oxide should be what?
