Calculate the number of atoms in a 2.70×10^3 g sample of carbon.
1. Use the thermodynamic data below to answer the following questions regarding this chemical reaction:
Determine the Ka of the ethylammonium ion (C2H5NH3+). [Kb of ethylamine (C2H5NH2) = 8.6 x10^-4]
Measurements on a MOSFET operating in the subthreshold conduction region indicate that the current changes by a factor of 10 for every 80-mV change in vGS and that Id = 20 nA at vGS = 0.16 V. Find the value of iD at Vgs = 0.
neon has a volume of 445 mL when it is at a pressure of 719 mmHg. What will be the volume when the pressure is increased to 1122 mmHg
A certain first-order reaction has a rate constant of 2.95×10-2s-1 at 22°C. What is the value of k at 61°C if Ea = 80.0kJ/mol ?
1) 10 mL of 0.05 M amino acid (Ka1=4.69x10^-3 and Ka2=1.79x10^-10) is titrated with 0.05 M HCl. Sketch a titration curve. (there's no need to actually sketch the curve; I just need to calculate the pH values needed to sketch a curve)
A reaction that is second-order in one reactant has a rate constant of 2.2 × 10-2 L/(mol · s). If the initial concentration of the reactant is 0.360 mol/L, how long will it take for the concentration to become 0.180 mol/L?
If the solution contains a metal cation such as \rm Ag^+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode.
Question- A 9.35L container holds a mixture of 2 gases at 35 degree Celsius. The partial pressure of gas A and B respectively are .438 atm and .789 atm. If .130 mol of a third gas is added, what is the total pressure
Estimate the amount of solar heating that is lost as a result of using one or two tempered 1/8 in thick glass plates covering a flat plate absorber. The transmission coefficient for radiation is 2% for wavelengths greater than 3 µm and 80% for wav..
what is the balanced chemical reactions when carbon dioxide reacts with water? how can carbon dioxide change the ph of
Suppose that a certain biologically important reaction is quite slow at physiological temperature (37 degrees C ) in the absence of a catalyst.
