13.98mL of 2.902M HCl are reacted with 15mL of 3.198M NaOH. Use the molar heat of neutralization to determine the kJ of heat produced.
If 842 J of heat is needed to increase the temperature of ethane gas (C2H6) in a 15 litre container from 237 K to 400 K, how much gas is in the container
1.7 mol of an ideal gas which starts at 1.6 atm and 50 o C does 2.0 kJ of work during an adiabatic expansion. What is the final volume of the gas?
Find the work for an isothermal expansion of 3.08 mol of an ideal gas at temperature of 18oC from pi = 4.55 atm to pf = 3.32 atm.
A container of volume 14.2 cm3 is initially filled with air. The container is then evacuated at 0oC to a pressure of 32 mPa. How many molecules are in the container after evacuation if we assume that air is an ideal gas?
"Calculate the internal energy for the air in human lungs after a regular inhalation. You find this volume discussed in the context of the spirometer (textbook p. 203). Hint: treat air as an ideal gas with the molecular mass M = 29.00 g/mol " Not sure the process to ...
what is the hybridization of BrO2+
4.0 g of ferrous ammmonium sulphate, FeSO4(NH4)2SO4 6H2O, is used. Since the oxalate is in excess, calculate the theoretical yield of the iron complex. Please help with this question. Thank you.
Hi Iam doing an article on why I think humans should not eat meat from the perspective of a parent with a child. I need three solid arguments for this; please help.
Hi, I am doing an paper on editors and their roles in broadcast. I wanted to get some ideas about how editors choose their lead story and why they are led to choose that story. Any ideas? thanks
