Enter its chemical formula: Of which reactant are there the least initial moles? Enter its chemical formula: Which reactant is the limiting reactant? Enter its chemical formula: Explanation Check

Consider the combustion reaction for octane (C,H2), which is a primary component of gasoline. 18 2 C3H13 + 25 0, → 16 CO, + 18 H,O How many moles of CO, are emitted into the atmosphere when 20.1 g C,H13 is burned? CO2 emitted: mol CO2

The complete combustion of gasoline (C8H18) is best represented by which of the following equations   Options:   2 C8H18 (l) + 25 O2 (g) → 16 CO2 (g) + 18 H2O(l)   2 C8H18 (l) + 17 O2 (g)  → 16 CO (g) + 9 H2O (l)   C8H18 (l) + O(g) → 8 CO2 (g) + 9 H2O (l)   C8H18 (l)  → 8 C (s) + 9 H2 (g)

Product Composition and Reaction Stoichiometry Suppose SH2 and O2 react to produce H20, and a sulfur oxide which contains 40.05% sulfur by mass. Complete the reaction equation by entering the coefficients of the reactants and products and also the empirical formula of the sulfur oxide product. SH2 + H20 + All coefficients must be reduced to the smallest possible integers. Note that, while it is not usual to write coefficients of exactly 1, you must enter "1" in the response box, if that is the correct value. The formula for the sulfur oxide must be written with the S symbol first and O second. The usual subscription of numbers in the formula is to be inferred (e.g. the formula for water would be entered simply as "H2O")

Hydrogen is manufactured on an industrial scale by this sequence of reactions: CH, (g) + H,0 (g) CO (g)+3 H, (g) K1 CO (g) + H,0 (g)= CO, (g)+H, (g) K2 The net reaction is: CH4 (g) +2 H,0 (g) CO, (g)+4H, (g) K Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K, and K,. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator. K

2NO(g) + O2(g) → 2NO2(g) You are provided with 4.12 molmol of nitrogen monoxide gas. Using the balanced chemical equation completed in Part A, determine how many moles of oxygen gas are needed to completely react with the nitrogen monoxide gas and how many moles of nitrogen dioxide are formed as a result? Ammonia and oxygen react to form nitrogen monoxide and water. Construct your own balanced equation to determine the amount of NO and H2O that would form when 2.80 molmol   NH3 and 4.64 mol O2 react. Express the amounts in moles to two decimal places separated by a comma.
