- Calculate the percentage composition for each of the following compounds (three significant figures). a NO b SO3 c NaH2PO3 d Pb(NO3)2arrow_forward3.96 Methyl cyanoacrylate is the chemical name for the substance sold as Super Glue, and it has the chemical formula C5H5NO2. Calculate the number of molecules of this substance in a 1.0-ounce tube of Super Glue, assuming that the glue is 80% methyl cyanoacrylate by mass.arrow_forward89 A number of compounds containing the heavier noble gases, and especially xenon, have been prepared. One of these is xenon hexafluoride (XeF6), which can be prepared by heating a mixture of xenon and fluoride gases. XeF6 is a white crystalline solid at room temperature and melts at about 325 K. A mixture of 0.0600 g of Xe and 0.0304 g of F2 is sealed into a 100.0-mL bulb. (The bulb is heated, and the reaction goes to completion. Then the sealed bulb is cooled back to 20.0°C. What will be the final pressure in the bulb, expressed in torr?arrow_forward
- The sugar sucrose, which is present in many fruits and vegetables, reacts in the presence of certain yeast enzymes to produce ethanol and carbon dioxide gas. Balance the following equation for this reaction of sucrose. C12H22O11(aq) + H2O(l) C2H5OH(aq) + CO2(g)arrow_forwardChalky, white crystals in mineral collections are often labeled borax, which has the molecular formula Na2B4O7 10H2O, when actually they are partially dehydrated samples with the molecular formula Na2B4O7 5H2O, which is more stable under the storage conditions. Real crystals of borax are colorless and transparent. (a) Calculate the percent mass that the mineral has lost when it partially dehydrates. (b) Is the percent boron by mass the same in both compounds?arrow_forwardExpress the composition of each of the following compounds as the mass percents of its elements. a. formaldehyde, CH2O b. glucose, C6H12O6 c. acetic acid, HC2H3O2arrow_forward
- How many total atoms does each of the following expressions, extracted from balanced chemical equations, represent? a. 2POCl3 b. 3H2O2 c. 6HClO3 d. Al2(SO4)3arrow_forwardYou have a pure sample of apholate, C12H24N9P3, a highly effective commercial insecticide. Calculate the molar mass of apholate. Calculate the mass of N in 100. g apholate. A sample containing 250.0 mg apholate is sprayed on an agricultural field. Calculate the mass of phosphorus in this sample of apholate; express your result in grams. Calculate the number of phosphorus atoms in this sample of apholate.arrow_forwardComplete the following table for TNT (trinitrotoluene), C7H5(NO2)3.arrow_forward
- When washing soda, Na2CO3, reacts with sulfuric acid, H2SO4, the equation is Na2CO3(aq) + H2SO4(aq) CO2(g) + H2O() + Na2SO4(aq) (a) Describe in words the meaning of this chemical equation. (b) Verify that the equation conforms to the law of conservation of matter.arrow_forwardConsider the chemical reaction 2 S + 3 O2 → 2 SO3. If the reaction is run by adding S indefinitely to a fixed amount of O2, which of these graphs best represents the formation of SO3? Explain your choice.arrow_forwardTwo general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different. (c) Heat the crucible again, and then reweigh it.arrow_forward
