Using the information (valid at 25 ºC): ΔfHº(NO2,g) = 33.18 kJ / mol ΔfHº(N2O4,g) = 9.16 kJ / mol and assuming that the molar heat capacities at constant pressure Cp, m(NO2,g) = 37.20 J / (K mol) Cp, m(N2O4,g) = 77.28 J / (K mol) are independent of temperature, calculate the standard enthalpy of the reaction 2 NO2(g) → N2O4(g) at 100 ºC and 1.0 bar.

This large tectonic plate is bounded on three sides by whats know as the ring of fire. what is the name of this tectonic plate? a) pacific plate b) eurasian plate c) north american plate d) indo- australian plate plz it's science but there's no option for science so i picked chemistry

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende
