What is the volume of the gas in milliliters when the pressure and temperature of the gas sample are changed to 634 and 301 ?
What volume will 1.56 liters of a gas at 27°C and 745 mmHg of pressure occupy at 100°C and 700 mmHg of pressure?
For the reaction of nitrogen monoxide, NO with chlorine, Cl2, 2NO(g) + Cl 2(g) -> 2NOCl(g) ; the observed rate law is : Rate = K[NO]^2 [Cl] What's the reaction order with respect to nitrogen monoxide? With respect to Cl2? What's the overall order?
What substance is produced at the anode during the electrolysis of a mixture of molten calcium bromide, CaBr2(l), and molten magnesium iodide, MgI2(l)? Assume standard conditions
write equations that show a plausible reaction mechanism for the acid-catalyzed isomerization of maleic acid
Ionization-type smoke detectors use the emissions from americium-241 to create a small electrical current in the detector, which sends out an alarm when smoke that enters the detector causes the current to decrease.
Calculate the wavelength of light necessary to provide photons of this energy? C) Explain why this film can be handled in a darkroom under red light.
Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.)
Calculate the change in pH when 3.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
When hydrochloric acid of 200 mL was mixed to a small piece of CaCO3 in the same calorimeter, the temperature increased by 4.25 degree celsius. determine the heat output for this reaction?
A 100. mL sample of 0.200 M aqueous hydrochloric acid is added to 100. mL of 0.200 M aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 480. J/K. The following reaction occurs when the two solutions are mixed.
what is the freezing point of solution made up of 54.9 g of NaCl dissolved in 800 g of water
