Liquid bromine dissolves readily in aqueous NaOH:Br2(€) + 2 NaOH(aq)NaBr(aq) + NaOBr(aq) + H,O(€)Suppose 2.88 × 10-3 mol of Br2(e) is sealed in a glass cap-sule that is then immersed in a solution containing excessNaOH(aq). The capsule is broken, the mixture is stirred,and a measured 121.3 J of heat evolves. In a separateexperiment, simply breaking an empty capsule and stirringthe solution in the same way evolves 2.34 J of heat. Com-putc the heat cvolvcd as 1.00 mol Br,(l) dissolves inexcess NaOH(aq).

Given, Br2 (l)+ 2 NaOH (aq) → NaBr (aq) + NaOBr (aq) + H2O (l) Moles of Br2 = 2.88 × 10-3 mol. Heat…

Propane, C3H8, is the fuel of choice in a gas barbecue. When burning, the balanced equation is C3H8+5O23CO2+4H2O a What is the limiting reactant in cooking with a gas grill? b If the grill will not light and you know that you have an ample flow of propane to the burner, what is the limiting reactant? c When using a gas grill you can sometimes turn the gas up to the point at which the flame becomes yellow and smokey. In terms of the chemical reaction, what is happening?
A titanium ore contains rutile (TiO2) plus some iron oxide and silica. When it is heated with carbon in the presence of chlorine, titanium tetrachloride, TiCl4, is formed. TiO2(s)+C(s)+2Cl2(g)TiCl4(g)+CO2(g) Titanium tetrachloride, a liquid, can be distilled from the mixture. If 35.4 g of titanium tetrachloride is recovered from 18.1 g of crude ore, what is the mass percentage of TiO2 in the ore (assuming all TiO2 reacts)?
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.
Potassium chromate, a bright yellow solid, is produced by the reaction of solid chromium ore (FeCr2O4) with solid potassium carbonate and gaseous oxygen at high temperatures. The other products of the reaction are solid iron (III) oxide and gaseous carbon dioxide. If you use 169.0g of chromium ore, 298.0g of potassium carbonate and 75.00g of oxygen in a sealed reaction vessel, what is the limiting reagent? Give the theoretical yield of potassium chromate, in grams, for each one.
Emissions from the burning of fossil fuels are often reported as gigatons ( Gt ) of carbon. In a calendar year, China emitted 2.9 Gt of carbon while the Unites States released 1.5 Gt of carbon. To what mass in gigatons of CO2CO2 do these amounts of carbon correspond?
320.4 grams of isomaltitol, C12H24O11, was combusted in a furnace completely in an excess oxygen. The products of this reaction are liquid water and gaseous carbon dioxide. How much water (in kg) do you expect from this reaction assuming that all of the isomaltitol reacts? Enter your numeric answer in the units of kg. Do not enter the unit. Use enough significant digits to prevent rounding errors. Hint: balance the reaction first. Recall that 1 kg = 1000 g.
Another component of acid rain is nitric acid, which forms when NO2, also a pollutant, reacts with oxygen and water according to the simplified equation 4NO2(g)+O2(g)+2H2O(l) → 4HNO3(aq) The generation of the electricity used in a medium-sized home produces about 16 kg of NO2 per year. Assuming that there is adequate O2 and H2O, what mass of HNO3, in kg, can form from this amount of NO2 pollutant? Express the mass to two significant figures and include the appropriate units.
Imagine that you are given 0.2500 g of a sample of copper(II) sulfate pentahydrate (CuSO4 • 5 H2O). You very carefully heat the compound for an extended period of time to drive off water, after which you determine the mass of the remaining solid to be 0.1598 g. Determine whether the data given confirm the formula of the hydrate. You must show any relevant calculation
Cryolite (Na3AlF6) is used in the commercial production of aluminum from ore. Cryolite itself is produced by the following reaction: 6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2O A mixture containing 420.0 kg of NaOH, 128.4 kg of Al2O3, and 600.0 kg of HF is heated to 950 °C until it reacts to completion. What is the maximum mass of Na3AlF6 formed? ________kg Na3AlF6
Consider the reaction:Fe(s)+Cl2(g)→FeCl3(s) How many moles of chlorine gas react with 0.300 molmol of metallic iron? Express your answer with the appropriate units.
Combustion of hydrocarbons such as decane ( C 10 H 22 ) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. A. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid decane into gaseous carbon dioxide and gaseous water. B. Suppose 0.270 kg of decane are burned in air at a pressure of exactly 1 atm and a temperature of 10.0 °C . Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has 3 significant digits.
One step in the isolation of pure rhodium metal (Rh) is the precipitation of rhodium(III) hydroxide from a solution containing rhodium(III) sulfate according to the following unbalanced chemical equation: Rh2(SO4)3(aq) + NaOH(aq) → Rh(OH)3(s) + Na2SO4(aq) If 3.10 g of rhodium(III) sulfate reacts with 5.90g of sodium hydroxide a. Determine the limiting reactant. b. Determine the excess reactant. c. What mass of rhodium (III) Hydroxide may be produced d. Calculate the percent yield if 1.3 g of rhodium (III) Hydroxideare actually obtained. MM of Rh2(SO4)3(aq) = 494g/mol MM of NaOH = 40g/mol) MM of Rh(OH)3(s) = 153.93g/mol
