One balloon is filled with helium, while the other contains argon. They are filled to equal volumes and contain the same number of atoms. Predict the relative masses of the gases in the two balloons.
What is the value of deltaH0 (in kJ) for the reaction described below. Assume the reaction is performed at 250C. C2H2 (g) + 2H2 (g) -----> C2H6 (g) a. - 248 b. - 311 c. - 173 d. 236
When maleic acid is heated to about 100C it forms maleic anhydride.however fumaric acid requires a much higher temperature
How much work is done when 18.0 grams of water vaporize at 100.°C under constant external pressure of 1.00 atm. The equation is: w=-P(delta change)V = -1.00atm * 30.62 L = -30.62 L atm ...and the answer is -3.10 kJ... How do you arrive at -3.10kJ ..
