A cylinder of gas is at room temperature (20°C). The air conditioner breaks down, and the temperature rises to 40°C. What is the new pressure of the gas relative to its initial pressure?
The mass spectrum of an organic compound shows the relative abundances of M to be 60.70% and M 1 to be 15.76%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound.
Some water dissolves in liquid methane at -161 degrees C, the boiling point of liquid methane, to give a solution in which the mole fraction of water is 6*10^-5. Determine the mass of water (in units of grams) dissolved in 115L of this solution if..
the practical benefits of using a more favorable direction of the reaction for a routine enzyme activity assay
If we wanted to prepare a buffer with boric acid and borate that had a final pH of 8.50, with a formal concentration of 0.10 M (i.e. 0.10 M = boric acid + borate), what concentrations of boric acid and borate do we need to use
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 subsequent reaction occurs when the two solutions are mixed.
Which of the following are exothermic and endothermic?
