The table shows element percentages for P 4 O 10 (tetraphosphorus decaoxide). We would speak of this equation as "one mole of molecular phosphorus reacts with five moles of elemental oxygen to make one mole of tetraphosphorus decoxide." ) reacts with water to produce phosphoric acid. Write the balanced equation for this reaction. Do not include states of matter in the equation. Use uppercase for the first character in the element and lowercase for the second character. Element % O: 56.36: P: 43.64: Isotope pattern for P 4 O 10. Write a balanced chemical equation based on the following description: solid tetraphosphorus decoxide can be synthesized from solid tetraphosphorus (Pâ) and oxygen gas. Write the balanced equation for this reaction. mol Now letâs assume that you have been transferred to the division responsible for the Tetraphosphorous decoxide (P 4 O 10 (Click in the answer box to activate the palette.) Exercise \(\PageIndex{1}\) Interpret this balanced chemical equation in terms of moles. 10.1 Equation Stoichiometry 415 The ratio of moles of P 4O 10 to moles of P (which came from the subscripts in the chemical formula, P 4O 10) provided the key conversion factor that allowed us to convert from units of phosphorus to units of tetraphosphorus decoxide. A) Tetraphosphorous decoxide(P4O10) reacts with water to produce phosphoric acid. Determine the number of moles of P 4 O 10 required to produce 5.80 moles of phosphoric acid. When 0.422 g of phosphorus is burned, 0.967 g of a white oxide (a compound of phosphorus and oxygen) is obtained. If 2.4g of magnesium burns in oxygen to produce 4.0g of magnesium oxide, Write a balanced equation for the reaction . Determine the empirical formula of the oxide. Convert the description into a balanced equation: A) When sulfur trioxide gas reacts with water, a solution of sulfuric acid forms. a. Phosphorus is just P and Oxygen is just O tetra=3 dec=10. 10.2 Real-World Applications of Equation Stoichiometry Letâs return to the reaction of solid tetraphosphorus decoxide and water. The balanced equation will appear above. ----- B) Determine the number of moles of P4O10 required to produce 4.40 moles of phosphoric acid. The chart below shows the calculated isotope pattern for the formula P 4 O 10 with the most intense ion set to 100%. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. what is the balnced equation for phosphorus burns in oxygen to produce tetraphosphorus decoxide 42,744 results Chemisty. P+O ---> 3P + 10O so clearly that is not ballanced, so on the other side add a 3 in front of the P and a 10 in front of the O and a very powerfull desiccant forming phosphoric aci. Tetraphosphorus decoxide, also known as diphosphorous pentoxide, is a white powder a.f.a.i.k. B) Phosphine, combusts in oxygen gas to form gaseous water and solid tetraphosphorus decoxide. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. phosphorus + oxygen -- tetraphosphorous decoxide. References. Science/ Chemistry. ----- C) Determine the number of moles of water required to produce 4.40 moles of phosphoric acid. Do not include states of matter in the equation.
