ou are given a sample that contains a mixture of the following two arsenic-containing minerals: getchellite (AsSbS3) and paakkonenite (Sb2AsS2). You start with a sample of this mixture that has a mass of 53.56 grams. You perform a reaction that converts the arsenic (As) in these minerals into the form iron(III) arsenate (FeAsO4), and 31.03 grams of this product are obtained. What is the percent by mass of getchellite in the original sample

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
