A 120 pound woman working in an office consumes about 2200 kcal/day, whereas the same woman climbing a mountain needs 3400 kcal/day. Express these numbers in terms of joules per second per kilogram of body mass ( = Watts per kilogram). Which consumes more power (watts), the office worker or a 100 W light bulb?
Decide whether or not the metal K dissolves in 1 M HCl. For this metal, if it does dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
Calculate the pH of each of the following strong acid solutions: 5.00 mL of 1.00 M HCl diluted to 0.500 L d) a mixture formed by adding 50.0 mL of 0.020 M HCL to 150 mL of 0.010 M HI
A sample of nitrogen gas in a 4.7-L container at a temperature of 28°C exerts a pressure of 3.6 atm. Calculate the number of moles of gas in the sample.
For a reaction of hydrogen with iodine, the rate constant is 2.45*10^-4 L mol-1 s-1 at 302 C and 0.950 L Mol-1 s-1 at 508 C.
