The space shuttle environmental control system handles excess CO2 (which the astronauts breathe out; it is 4.0% by mass of exhaled air) by reacting it with lithium hydroxide, LiOH, pellets to form lithium carbonate, Li2CO3, and water. If there are seven astronauts on board the shuttle, and each exhales 20. L of air pee minute, how long could clean air be generated if there were 25,000 g of LiOH pellets available for each shuttle mission? Assume the density of air is 0.0010 g/mL.
Beta-blockers are a class of drug widely used to manage hypertension. Atenolol, a beta-blocker, is made up of carbon, hydrogen, oxygen, and nitrogen atoms. When a 5.000-g sample is burned in oxygen, 11.57 g of CO2 and 3.721 g of H2O are obtained. A separate experiment using the same mass of sample (5.000 g) shows that atenolol has 10.52% nitrogen. What is the simplest formula of atenolol?
A 0509-g sample of an unknown organic compound containing C, H, and O was burned in air to give 1.316 g of CO2 and 0.269 g of H2O. What is the empirical formula for this compound? (a) CHO (b) C2H2O (c) C4H4O (d) CHO4
Copper metal reacts with mine acid. Assume that the reaction is 3Cu(s)+8HNO3(aq)3Cu(NO3)2(aq)+2NO(g)+4H2O(l) If 5.58 g Cu(NO3)2 is eventually obtained, how many grams of nitrogen monoxide, NO, would have formed?
3.50 A test of an automobile engine's exhaust revealed that g of NO2 was emitted in 10 minutes of operation. How many moles of NO2 would this engine release if it were used for a 45-minute commute, assuming that this mea- sured number is representative of the emission under all circumstances?
To find the empirical formula of tin oxide, you first react tin metal with nitric acid in a porcelain crucible. The metal is converted to tin nitrate, but, on heating the nitrate strongly, brown nitrogen dioxide gas is evolved and tin oxide is formed. In the laboratory you collect the following data: What is the empirical formula of tin oxide?
Pls help on both questions.
A pure sample of a hydrocarbon, a compound containing only hydrogen and carbon, was burned in the presence of excess oxygen gas. The results showed that 58.7 g of CO2 and 27.0 g of H2O were produced. Which of the following is the empirical formula for the compound? (MM of CO2 is 44 g/mol and MM of H2O is 18 g/mol) C2H5 СЗН5 CH2 O C4H9
1.) The combustion of ammonia in the presence of excess oxygen yields NO2 and H2O: 4NH3 (g) + 7O2 (g) ---> 4NO2 (g) + 6 H2O (g) The combustion of 43.9 g of ammonia produces ____g of NO2
Hydrofluoric acid (HF) can be prepared according to the reaction: CaF2 + H2SO4 à 2 HF + CaSO4. In one experiment, 42.0 g of CaF2 was treated with excess H2SO4 and a yield of 14.2 g of HF was obtained. What is the theoretical yield of HF? (show work please)
(Incorrect) Dolomite is a mixed carbonate of calcium and magnesium that decomposes to CO2 and the metal oxides MgO and CaO upon heating. When 12.06 g of dolomite is heated, 6.45 g of MgO and CaO are produced. What is percent by mass of MgCO3 in the original sample of dolomite? 30.9% (Correct answer) 3.73% 69.1% (Your answer) 34.7% 8.33%%
3.) What mass (in grams) of fluorine gas (F2) is needed to react completely with 17.8 g of sulfur (S8), to form sulfur hexafluoride (SF6)? S8 (g) + 24 F2 (g) ---> 8 SF6 (g) Molar Masses: 1 mole of F2 = 38 grams of F2 %3D 1 mole of S8 = 256.48 grams of S8 Ratio: 24 mole of F2 = 1 mole of S8
