Webb26 nov. 2024 · equation 1: P4 + 5O2 → 2P2O5 ΔH1 equation 2: 2P2O5 + 6H2O → 4H3PO4 ΔH2 equation 3: P4 + 5O2 + 6H2O → 3H3PO4 ΔH3. Enthalpy is a state function which means the energy change between two states is independent of the path. Since equation 1 and 2 add to become equation 3, we can say: ΔH3 = ΔH1 + ΔH2.

Webb45.0 grams of F2 react according to the following balanced chemical equation: F2 + 2NaI arrow I2 + 2NaF As a result of this reaction, how many grams of I2 are produced? How many moles of CO2 are produced when 76.5 grams of HCl are produced in the following reaction? 2C12H4Cl6 + 23O2 + 2H2O arrow 24CO2 + 12HCl Webb10 feb. 2015 · 1. Lets break the problem into 2 parts: ( 6 h + k − 2) ( 2 h − 3) and − ( 4 h − 3 k) 2. Expand the first part and you will get: 12 h 2 + 2 h k − 22 h − 3 k + 6. Expand the second part and you will get: − 16 h 2 + 24 h k − 9 k 2. Then simply combine like terms in both expressions together and the answer is: − 4 h 2 + 26 h k − ... phil narkle artist
