When 1 mole of propane (C3H8) is burned at a constant pressure 2221 kJ of energy is released as heat. Calculate Delta H for a process in which 25.0 g of propane is burned at a constant pressure

6because i no yea yea

Ametal with a large number of free flowing electrons most likely has good conductivity

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.
