Given the following equations, calculate the δh of the reaction of ethylene gas (c2h4) with fluorine gas to make carbon tetrafluoride (cf4) gas and hydrogen fluoride gas. show your work. h2 (g) + f2 (g) → 2hf (g) δh = –537 kj c (s) + 2f2 (g) → cf4 (g) δh = –680 kj 2c (s) + 2h2 (g) → c2h4 (g) δh = +52.3 kj

Using the thermodynamic information in the aleks data tab, calculate the standard reaction free energy of the following chemical reaction: →+p4o10s6h2ol4h3po4s round your answer to zero decimal places.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
