A layer of sediment goes through a series of steps on its way to becoming sedimentary rock

There are two steps in the extraction of copper metal from chalcocite, a copper ore. in the first step, copper (i) sulfide and oxygen react to form copper (i) oxide and sulfur dioxide: (s) (g) (s) (g) in the second step, copper (i) oxide and carbon

The following data are for the reaction 2NO (g) + O2 (g) → 2NO2 (g) at some temperature. Experiment 1: [NO] = 0.0070 M; [O2] = 0.0070 M; rate = 9.6 10-1 M/s. Experiment 2: [NO] = 0.0070 M; [O2] = 0.014 M; rate = 1.9 M/s. Experiment 3: [NO] = 0.

A 1.268 g sample of a metal carbonate, MCO3, was treated 100.00 mL of 0.1083 M H2SO4, yielding CO2 gas and an aqueous solution of the metal sulfate. The solution was boiled to remove all of the dissolved CO2 and then was titrated with 0.1241 M NaOH.
