At what temperature will He atoms have the same Crms value as N2 molecules at 25 degrees Celsius? Solve this problem without calculating the value of Crms for N2. Crms is the root mean square speed.
A 93.7 g (5.20 mole) sample of water is heated to exactly 94.4 celsius. It is then added to 90.1 g (5.00 mole) of water at 22.5 celsius in a styrofoam cup calorimeter.
The student then titrated 25ml of the same buffer with 0.1115M NaOH. The observed titration curve is shown before. what is the concentration of the weak acid in the buffer?
Calculate the final temperature when a 22.0 gram sample of ice at 0oC is placed into a styrofoam cup containing 113 grams of water at 77.1 oC. Assume that there is no loss or gain of heat from the surroundings.
If a second experiment is done with half as much H2O2 as the experiment in question 1, and the solution turns blue in 180 seconds, what is the order of the reaction with respect to H2O2?
The half life of Iodine-131 is 8.0252 days. If 14.2 grams of I-131 is released in Japan and takes 31.8 days to travel across the Pacific
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C2H6(g)+H2(g) 2CH4 the standard change in Gibbs free energy is
she decomposes the mixture in the exact same manner as the lab, and isolates 154 mL of water at the end. if the water temperature is 24oC and the atmospheric pressure is 742 torr, what was the percent by mass of mercury oxide in the mixture
the relevant masses for this decay, and calculate the energy (in MeV) released by the decay of one such atom. You can neglect the mass of the neutrino that is one of the decay products.
Using a single reagent and only reaction chemistry that was part of this experiemnt, how could you distinguish between the following pair of substances contained in seperate test tubes?
The first-order rearrangement of CH3NC is measured to have a rate constant of 3.61 x 10-15 s-1 at 298 K and a rate constant of 8.66 × 10-7 s-1 at 425 K. Determine the activation energy for this reaction.
Hydrogen gas produced in the laboratory by the reaction of zinc and hydrochloric acid was collected over water at 25°C. The barometric pressure at the time was 742.5 mm Hg.
A crystalline unit cell contains oxygen atoms on all edges of the cell and rhenium atoms on each corner. What is the formula for rhenium oxide
