Concept introduction:
(b)
Interpretation:
The conservation of mass law using the molar masses of reactants and products for each substance for the given reaction is to be illustrated.
Concept introduction:
Chemical reactions are represented by chemical equations. In a chemical equation the reactants are represented on the left of the arrow while the products are represented on the right of the arrow. Stoichiometric coefficient is the number preceding each symbol in a reaction which determines the moles of the reactants and products in the reaction. The ratio of moles is termed as mole ratio. It is stated by law of conservation of mass that, “during any chemical reaction, the mass of product must be equal to mass of the reactants”.

- 4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.arrow_forwardGiven that the density of argon is 1.78 g/L under standard conditions of temperature and pressure, how many argon atoms are present in a room with dimensions 4.0 m 5.0 m 2.4 m that is filled with pure argon under these conditions of temperature and pressure?arrow_forwardBoth water and sulfur dioxide are products from the reaction of sulfuric acid (H2SO4) with copper metal, asshown by the equation 2H2SO4 + Cu SO2 + 2H2O + CuSO4 How many grams of H2O will be produced at the same time that 10.0 g of SO2 is produced?arrow_forward
- White phosphorus, P4, is prepared by fusing calcium phosphate, Ca3(PO4)2, with carbon, C, and sand, SiO2, in an electric furnace. 2Ca3(PO4)2(s)+6SiO2(s)+10C(s)P4(g)+6CaSiO3(l)+10CO(g) How many grams of calcium phosphate are required to give 30.0 g of phosphorus?arrow_forwardHydrogen cyanide is produced industrially from the reaction of gaseous ammonia, oxygen, and methane: 2NH3(g)+3O2(g)+2CH4(g)2HCN(g)+6H2O(g) If 5.00 103 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?arrow_forward4.104 When 2.750 g of the oxide Pb3O4 is heated to a high temperature, it decomposes to produce 0.0640 g of oxygen gas and 2.686 g of some new lead oxide compound. How can you use these data to determine the formula of the new compound?arrow_forward
- Boron forms an extensive series of compounds with hydrogen, all with the general formula BxHy. To analyze one of these compounds, you burn it in air and isolate the boron in the form of B2O3 and the hydrogen in the form of water. You find that 0.1482 g BxHy gives 0.4221 g B2O3 when burned in excess O2. Determine the empirical I formula of BxHy.arrow_forwardThe active ingredient in Pepto-Bismo® (an over- the-counter remedy for an upset stomach) is bismuth sub-salicylate, C7H5BiO4. Analysis of a 1.7500-g sample of Pepto-Bismol yields 346 mg of bismuth. What percent by mass is bismuth subsalicylate in the sample? (Assume that there are no other bismuth-containing compounds in Pepto-Bismol.)arrow_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_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_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_forwardA sample of sandstone consists of silica, SiO2, and calcite, CaCO3. When the sandstone is heated, calcium carbonate, CaCO3, decomposes into calcium oxide, CaO, and carbon dioxide CaCO3(s)CaO(s)+CO2(g) What is the percentage of silica in the sandstone if 18.7 mg of the rock yields 3.95 mg of carbon dioxide?arrow_forward
