How many liters of N2 (at STP) form when 1.0 kg N2H4 react with 1.0 kg O2? I am really confused on this problem pleas help me. The standard enthalpy of reaction, [latex]\Delta H^\ominus _{rxn}[/latex], is the change in enthalpy for a given reaction calculated from the standard enthalpies of formation for all reactants and products.

asked by Alekya on July 9, 2007; chemistry-Thermochemistry (grade 12) How do the densities compare. The volume of any gas, under any temperature or pressure conditions will depend on the amount of gas you have.

calculate the density of N2 at STP using (a) the ideal gas law (b) the molar volume and molar mass of N2. Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. How many grams of excess reagent remain after the reaction?

Find an answer to your question What is the enthalpy of reaction for the decomposition of NO2(g)? N2H4(l)+O2(g)(arrow)N2(g)+2H2O(g) a. standard enthalpy of reaction: The enthalpy change that occurs in a system when one mole of matter is transformed by a chemical reaction under standard conditions. STP only identifed the temperature (273 K) and pressure (101.3 kPa). 2NO2(g) → N2(g) + 2O2(g) KJ This reaction is THE ANSWER IS -67… Density of the gas is related to molar mass, pressure and the temperature by the rearranged ideal gas equation below. Step 1. 1 . check_circle Expert Answer. b. Answer to: What is the density of nitrogen gas (N2) at STP?
