Question

Discussion #7 --OH HO HO 1o. 1. Define Stoichiometry? 2.Based on the following equation: 4 NH3 + 702 --> 4 NO2 + 6H2O Calculate the mass of O2 needed to react with 3.13 g of NH3. 3. Leave to your classmates one hint/trick that helps you to solve stoichiometry problems.

Answer 1

Discussion #7 Stoichiometry - When two of more substances undergoes a physical the quantitative or Chemical change in a chemical reaction, then relationship between these . substances is called stoichiometry ... or . The relationship between the ratio of two of more substances is called stoichiomelly. This is based on law of conservation of mass which states that matter can neither created nor it is destored the mass of enery element en reactauts in a chemical reaction = ' mass of every element en products, a calculate the mass of op needed to react with 3.13 g of NM3. U NH3 +702 4NO2 + 6H₂O Hmoles of NH2 reacts with of moles of i moll of it O. reacts with Z moles of 02 (3 43 Amer) mole og mang ore ack with Example pres) mol ayos Hence, mass og , need = x 343 mm ep x l6gimel = 5.1559.0, [:molar mass op n = 1691m 08] 179
