Ethylene (C2H4 = 28.05 g/mol) burns in oxygen (O2 = 32 g/mol) to form carbon dioxide (CO2
= 44.01 g/mol) and water vapor (H20 = 18.02 g/mol):
C2H4(9) + 3 O2(g) → 2 CO2(g) + 2 H2O(g)
How many liters of carbon dioxide can be formed if 4.93 liters of ethylene are consumed in

Harvey mixes two liquids. which observation of the new mixture most likely indicates a precipitate is forming?

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 .
