The CO2 exhaled by astronauts must be removed from the spacecraft atmosphere. One way to do this is with solid LiOH:CO2(g) + 2 LiOH(s) Li2CO3(s) + H2O(l)
The CO2 output of an astronaut is about 1.3 kg/day. What is the minimum mass of LiOH required for a six-day space shuttle flight involving five astronauts?
Calculate the Ki for a competitive inhibitor whose concentration is 6.5 x10-5 M that increases the Km of the substrate by 24.5%.
If a sample of 0.190 grams of KCN is treated with an excess of HCL, calculate the amount of HCN formed, in grams.
would that be the same kind of functional group linking monosaccharides in long chain polysaccharides
a 5.00 gram sample of potassium chlorate/potassium chloride mixture was heated in a test tube. A total of 1.00 L of oxygen gas was collected over water at 25 degrees c and 741 torr. determine the percentage of potassium chlorate in the mixture.

A steel cylinder of oxygen has a volume of 20.0 L at 22degrees C at 35 atm. What is the volume at STP? How many mol of oxygen
Description of Chemical Reactions, Why when heating and cooling three different separate substances in open containers does the mass change in two of them (one loss mass; the other gained mass) but stays the same in the third when it is known that..
An anesthetic contains 64.9 % carbon, 13.5 % hydrogen, and 21.6 % oxygen by mass. At 120 degrees C and 750 mmHg, 1.00 L of the gaseous compound weighs 2.30 g.
