Answer: 1 on a question How many moles of h3po4 are produced when 71.0g p4o10 reacts completely to form h3po4? Upon hitting submit, the stoichiometric equivalents will be calculated for the remaining reactants and products. volume gas oksigen (STP) yang - 15024… Mass = mole x molar Mass Mass of P4O10 = 2 x 284 Mass of P4O10 = 568g Therefore, the theoretical yield of P4O10 is 568g. Get the detailed answer: The balanced equation is P4O10(s) + 6H2O(l) yields 4H3PO4(l). The Calitha - GOLD engine (c#) (Made it possible for me to do this program in C#) Even though the structure of the compound contains four phosphorous and ten oxygen chemists always refer to this material as P2O5 ( four and ten ca... Phosphoric acid can be made from phosphorus in a two step process: Reaction 1: P4 + 5 O2 --> P4O10 Reaction 2: P4H10 + 6H2O--> chemistry. 4.00 mol c. 1.00 mol d. 16.0 mol - the answers to answer-helper.com What mass of water can be absorbed by 1.00 ( 102 g of P4O10? 107 g P4O10 B. Calorimetry • It is prepared by treating P4O10 with boiled water. For the reaction P4O10(s) + 6H2O(l) → 4H3PO4(aq), what mass of P4O10 must be consumed if 1.68× 10^23 molecules of H2O are also consumed? 1) Determine the moles of each reactant and thus the limiting reagent: # moles= mass (g)/M r . (实际上我们会使用浓硫酸,产生大量no2),成本较低而且较容易处理,与其他更强的脱水剂,例如p4o10,也可以产生大量的硝酰阳离子,这是硝化反应能进行的本质。 参考资料来源:百度百科-硝酸 grams = moles x … What is the limiting reagent and thus the mass of product for the reaction: P4O10 + 6H2O --> 4H3PO4 if 5.00 g of P4O10 react with 1.50 g of water? Phosphine, PH3, a reactive and poisonous compound, reacts with oxygen as follows: 4PH3(g) 8O2(g) – P4O10(s) 6H2O(g) If you need to make 6.5 moles of P4O10, how many moles of PH3 is required for the reaction 51. P4O10 (s) + 6 H2O (ℓ) → 4 H3PO4 (aq) Back to reactions list . 0.063 5 mol b. Pastebin.com is the number one paste tool since 2002. Stoichiometry. Phosphorus pentoxide has … P4O10 + 6H2O ==> 4H3PO4. a) The reaction equation; P4O10 + 6H2O-> 4H3PO4 H3PO4 = 283 Mass = weight/ gm.wt = 14/283 Concentration = … a. Answer Comment. Group of answer choices P4O10 + 6 H2O --> 4 H3PO4. Create a System of Equations, One Per Element P: 4a + 0b = 1c O: 10a + 1b = 4c H: 0a + 2b = 3c 3.
