One method of removing CO2(g) from a spacecraft is to allow the CO2 to react with LiOH. What volume, in liters, of CO2(g) at 28.7°C and 738 Torr can be removed by 1.36 kg LiOH?
2 LiOH(s)+CO2(g)→Li2CO3(s)+H2O(l)
Enter scientific notation as 1.23E4.
Enter only numbers in your answer. (Do not include units.)
Lakes that have been acidified by acid rain can be neutralized by liming, the addition of limestone (CaCO3). How much limestone in kilograms is required to completely neutralize a 3.8 x 109 L lake with a pH of 5.5
Since you need pressure based constant use ideal gas equation (PV=nRT) to convert moles of gas into pressure with units of atmospheres. R=0.0821 L atm/mol K
Enter the compound formula, including state, of the missing substance ( Y ) in the balanced equation below. Do not give the coefficient. Polyatomic ions only need parentheses when there is more than one of the given ion in the molecular formula.
Draw the potential unwanted byproduct in the reaction of cyclohexanol with sulfuric acid and aqueous sodium bromide.
What is the pH at the half-stoichiometric point (that is, what is the pH when you have added 50% of the total volume of base required to react with all of the acid originally present?)
