We consider the following chemical equation: 6 HCl + Fe2(CO3)3 +3 Ca(OH)2
- 2 FeCl3 + 3 CaCO3 + 6 H2O
How many moles of CaCO3 would be obtained from 0.7 moles of Fe2(CO3)3, 2.2 moles of Ca(OH)2 and
2.75 moles of HCI? How many grams of FeCl3 would be produced?
sosss :(

Chen drew a diagram to compare the ways in which different organisms obtain nitrogen. which label belongs to the area marked z?

An object displaces 652 ml of water. the volume of the object is: 0.652 cm³ 6.52 cm³ 65.2 cm³ 652 cm³

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 .
