As early as 1938, the use of NaOH was suggested as a means of removing CO2 from the cabin of a spacecraft according to the following (unbalanced) reaction: NaOH + CO2 → Na2CO3 + H2O.
If the average human body discharges 925.0 g CO2 per day, how many moles of NaOH are needed each day for each person in the spacecraft?
How many moles of each product are formed?
What is the maximum number of electrons that can be identified with each of the following sets of quantum numbers? In some cases, the answer may be "none."
An 11.0 gram sample of CaCl2(s) is dissolved in 125 grams of water with both substances at 25.0°C. If the final temperature of the mixture is 39.2 °C.
