The complete electron configuration of: Beryllium Fluorine Aluminum The noble gas configuration of: Iron Yttrium Bromine Fe+3 Ba+2 As-3
degree celsius in a heat exhanger by 54430 kg/h of hot gas flowing counterflow and entering at 427 degree celsius. (Cpm=1.005 kj/kg*K). The overall Uo=69.1 W/m^2*K. Calculate the exit gas temperature and the heat transfer area.
what volume will 5.90 moles of sulfur hexafluoride (SF6) gas occupy if the temperature and pressure of the gas are 159 C and 5.50 atm, respectively
When 1 mol of a gas burns at constant pressure, it produces 2414J of heat and does 4kJ of work. 1. Identify \Delta E for the process. Express your answer using one significant figure.
It is possible to define metallic character as we do in this book and base it on the reactivity of the element and the ease with which it loses electrons.
Vapor Pressure due to water at 24oC: 22.4 torr For the conditions listed above, calculate the volume of O2(g) produced at standard conditions of temperature and pressure.
Cyclopropane, C3H6, is an anesthetic given by inhalation. How many grams are in 0.30 mole of cyclopropane? The sedative Demerol hydrochloride has the formula C15H22ClNO2. How many grams are in 2.2x10^-2 mole of Demerol hydrochlorde?
