17. In aqueous solution, metal oxides can react with acids to form a salt and water: Fe2O3(s) + 6 HCl(aq) → 2 FeCl3(aq) + 3 H200
How many moles of each product will be formed when 35 g of Fe2O3 react with 35 g of HCI?
A. 0.32 mol FeCl3 and 0.48 mol H2O
B. 0.54 mol FeCl3 and 0.21 mol H2O
C. 0.76 mol FeCl3 and 0.32 mol H2O
D. 0.27 mol FeCl3 and 0.89 mol H2O

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

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 .
