(4 points each) (a) 241 +312 -2A113 (b) Ba(OH)2 + HBI BaBr 2 + H2O (c) C&H 206 + O2 → 10. What volume of a 2.00 M solution of AuCl2 would be necessary to give 1.65 g of AuCiz? (5 points) 11. A solution of KOH was titrated with 0.1423 g of HBr. If 3.08 mL of KOH solution were...
#4 4) Two containers of equal volume each hold samples of the same ideal gas. Container A has twice as many molecules as container B. If the gas pressure is the same in the two containers, the correct statement regarding the absolute temperatures TA and TB in containers A and B, respectively, is A) TA- JIB B) TA =TB. C) TA = 2TB. D) TA = TB. E) TA=TB:
If O2(g) and H2(g) are in separate containers of equal pressure, volume and temperature, which one of these statements is true? The amount of moles in the O2 container is greater than that in the H2 container. There are more molecules in the H2 container than molecules in the O2 container. If you increase the pressure in both containers, but keep temperature constant, the volume of both containers will increase If you increase the pressure in both containers, but keep...
Equal masses of CO2 and CH4 gas are placed in identical 1.00 L containers, both at the same temperature. Which of the following is true? X. Both gases exert the same pressure. Y. Molecules of CH4 make more frequent collisions with the walls of the container. Z. Both gases have the same average molecular speed. answer can be more than one
Quantitative Problems 3.) (Knight -18.73) Containers A and B hold the same gas. The volume of B is 4 times larger than the volume of A. The two containers are connected by a thin tube with negligible volume and a valve that is closed. The gas in A is at a temperature of 300K and a pressure of 10°Pa and the gas in B is at a temperature of 400K and 5x105Pa. Heaters maintain the temperature of the containers even...
Question 4 of 10 If two separate containers A and B have the same volume and temperature, but container A has more gaseous molecules than B, then container A will have:
ests volume le V at constant ressur ontainerta o estsvol me at constant Two containers hold equal amounts o he same deal atomic gas. They n tia have pressure and volume V on ainer #1 do temperature. Compare the heat flow during the two processes. Remember, positive Q means that heat flows into the container. a. 01402 O Cannot be determined
22. Consider two gases, A and B, in containers of equal volume. Both are at the same V, T and P: mass A: 0.34 g and mass B: 0.48 g. Are the following statements true or false? Why? a. The molar mass of A is greater than the molar mass of B b. Both samples have the same average kinetic energy. c. The molecules of A have the same average velocity as the molecules of B d. The molecules of...
A researcher wishes to use two identical containers (i.e. having the same volume), one to store 5 moles of O2 gas, and one to store 3 moles of N2 gas. Both are kept at 300 K and 5 atm. Is this possible? O Yes, since O2 and N2 have different molar masses. O Yes, since these conditions are not at STP. O Yes, since gases can be compressed. O No, because number of moles and temperature are directly proportional. No,...
