What is the ratio of moles of NH3 to moles of NO in the following equation? I went to a Thanksgiving dinner with over 100 guests. The chief was seen coughing and not wearing a mask.

Get your answers by asking now. So, 5 mol of O2 is needed to react with 4 mol of NH3. how many grams of O2 are needed to completely react with 68.12 g of NH3? First you have to balance the reaction to determine the mole ratios of the reactants and products. 4NH3 + 5O2 4NO + 6H2O The mole fraction between the NH3 and NO is therefore 4:4 or 1:1. Should I call the police on then? In order to balance NH3 + O2 = NO + H2O you'll need to watch out for two things. So there is not enough oxygen to react with all the ammonia. Don't forget the H2O on the product side of the chemical equation! Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Finally, to determine the mass, use the same formula above: mass = 5 mol O2 x 32.00 g/mol O2 = 160. g O2 needed. NH3 + O2 = NO + H2O - Chemical Equation Balancer. So there will be some ammonia left. Getting back to the 42 moles of O2, it will react with 4/5th as many moles of ammonia or about 33 moles. Reaction Type. Since NO is formed in a 1:1 ratio with ammonia, we form 33 moles of NO. NH3 (g) + O2 (g) = NO (g) + H2O (g) - edu-answer.com Finally, to determine the mass, use the same formula above: moles = mass / molar mass. Did McCracken make that monolith in Utah? ★★★ Correct answer to the question: 2. And the respond could be 4.seventy 8 x 4/5 or 3.824 moles of NO. and you need to around off to 3.eighty two moles to maintain the comparable style of considerable digits. So, 5 mol of O2 is needed to react with 4 mol of NH3. Remember the moles of the unknown is in the numerator. Reaction stoichiometry could be computed for a balanced equation. Ammonia + Dioxygen = Nitric Oxide (radical) + Water . In this example, the amount given is exactly equal to the mole ratio; however, this will rarely be the case. 4 NH 3 + 5 O 2 → 4 NO + 6 H 2 O. Therefore, you need to balance this reaction: 4NH3 + 5O2 --> 4NO + 6H2O. So the conversion factor would be 4/5. which makes you more jittery coffee or tea? mass = moles x molar mass Drawing/writing done in InkScape on a Wacom tablet.. Screen capture done with Camtasia Studio 4.0. First you will be able to desire to stability the reaction to ascertain the mole ratios of the reactants and products. So the molar ration is 5 to 4. First, be sure to count all of N, H, and O atoms on each side of the chemical equation. Join Yahoo Answers and get 100 points today. Scaling up to our problem the ratio of NH3/O2 is slightly less than 1. The balanced reaction is: 4NH3 + 5O2 --> 4NO + 6H2O So the molar ration is 5 to 4 So the conversion ingredient could be 4/5. Which of the following can be characterized as a strong electrolyte? Write the formula for the compound that has the atoms and, or groups in the order given: 3 Fe, and two groups made up of 1 As and 4 O.. Get an answer to your question “Use the unbalanced equation NH3+O2--> NO+H2O to find the mole ratio between NH3 ad O2 ...” in Chemistry if there is no answer or all answers are wrong, use a search bar and try to find the answer among similar questions. Enter either the number of moles or weight for one of the compounds to compute the rest. This ratio will not change, so if you are given a different amount of reactant or product, you can always use this same ratio to determine the unknown amount. From the balanced reaction, you need 4 moles of NH3 to react with 5 moles of O2. 4 mol NH3 = 4 mol NH3----- -----5 mol O2 = x mol O2. The balanced reaction is: 4NH3 + 5O2 --> 4NO + 6H2O. To convert grams to moles, you divide by the molar mass of the compound/element: moles = 68.12 g / 17.03 g/mol = 4 mol NH3, The balanced chemical equation tells you the fundamental ratio between reactants and products. The first thing that needs to be done in order to answer the question above is to balance first the chemical equation by seeing to that the number of moles of a certain element on the reactant side is equal to the number of moles in the product side. To determine the amounts needed in a chemical equation, you always have to convert the quantity given to moles. submit to in concepts the moles of the unknown is interior the numerator. Examples of complete chemical equations to balance: Fe + Cl 2 = FeCl 3 In order to balance NH3 + O2 = NO + H2O you'll need to watch out for two things. Reaction Information. And the answer would be 4.78 x 4/5 or 3.824 moles of NO. Double Displacement (Metathesis) Reactants. Still have questions? Balanced Chemical Equation. In this example, the amount given is exactly equal to the mole ratio; however, this will rarely be the case. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance the equation.Be careful when counting the Oxygen atoms on the product side of the equation.
