Is a first order rate constant of 3.14x10^-4 1/s at room temperature, if you currently have a 2.5 M N2O5 how long will it take for 65% of N2O react?
A 7.50 piece of iron at 100*C is dropped into 25.0g of water at 22.0*C. Assuming that the heat lost equals heat gained, determine the final temperature of the iron/water system. Assume a heat capacity of water of 4.18J/gK and of iron of 0.45J/gK.
oxygen molecules absorb uv radiation of wavelength less than and equal to 242 nm calculate the frequency and energy of the least energitic of these photons.
When the compound spontaneously decomposes, the piston moves up, the temperature of the water reaches a maximum of 29.52 C, and then it gradually decreases as the water loses heat to the surrounding air.
