Gaddis states that the leaders who were in power toward the end of the Cold War were only able to challenge the way things were and neutralize the forces that had perpetuated the Cold War because the policy of détente collapsed. What caused the collapse of détente, and how do you think this collapse contributed to the outcome of the Cold War?
"the most fundamental task of any effective strategy: the efficient use of available means to accomplish chosen ends." Do you agree or disagree with this statement? What evidence draws you to your conclusion?
What are the 3 major functional groups in an aspirin molecule?
SO42−(aq)+4H+(aq)+2Br−(aq) --> Br2(aq)+SO2(g)+2H2O(l)
Q= 1.9 x 10^-27
What pH is needed to produce this value of Q if the concentration and pressure values are
• [Br2]= 2.50×10^−4M
• [Br−]= 11.40M
• [SO42−]= 9.35M
• PSO2= 3.50×10^−5atm
A student designs an ammeter (a device that measures electrical current) that is based on the electrolysis of water into hydrogen and oxygen gases. When electrical current of unknown magnitude is run through the device for 3.00min, 13.4mL of water-saturated H2(g) is collected. The temperature and pressure of the system are 25 ∘C and 715 torr.
Calculate the magnitude of the current in amperes if the number of moles of hydrogen gas produced is 4.98×10−4mol.
T (∘C) P (torr)
Suppose that a fully charged lead-acid battery contains 1.50 L of 5.00 M H2SO4. What will be the concentration of H2SO4 in the battery after 2.10A of current is drawn from the battery for 8.50hours?
A lead-acid battery uses a redox reaction in which lead(0) and lead(IV) are both converted to lead(II). This reaction is facilitated by the presence of sulfuric acid, H2SO4, as shown by the reaction
Pb+PbO2+2H2SO4→2PbSO4 --> 2PbSO4 + 2H2O
PLEASE HELP!!Calculate the amount of energy in kilojoules needed to change 441g of water ice at -10 degrees Celsius to steam at 125 degrees?
Calculate the amount of energy in kilojoules needed to change 441g of water ice at -10 degrees Celsius to steam at 125 degrees Celsius. The following constants may be useful:
Cm (ice)=36.57 J/(mol⋅Celsius)
Cm (water)=75.40 J/(mol⋅Celsius)
Cm (steam)=36.04 J/(mol⋅Celsius)
A beaker with 135mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in...?
A beaker with 135mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.50mL of a 0.400M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
PLEASE HELP!! I'm confused!
