Propenoic acid, C3H4O2, is a reactive organic liquid that is used in the manufacturing of plastics, coatings, and adhesives. An unlabeled container is thought to contain this liquid. A 0.256-g sample is combusted to produce 0.170 g of water and 0.262 g of carbon dioxide.

Calculate the experimental mass % of C and H in the unknown liquid used in the experiment.

Express your answers, separated by commas, to three significant figures.

    DISCUSSION QUESTIONS 1. If the liquid did not completely vaporize in the experiment, would the ap- parent molecular weight be larger, smaller, or unchanged compared to that determined if the experiment had been properly performed? Would the error in part (1) have a larger, smaller, or the same effect as the errors that might be made in measuring the temperature of the water in the flask, the barometric pressure, or the volume of the flask? Explain your answer. 2. What...

    Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...

    Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....

    1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l)  → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...
