15.45 grams of solid potassium chlorate decomposes when heated to form solid potassium chloride and oxygen gas. Assuming 100% yield, how many grams of solid potassium chloride will be produced? Solid magnesium combines with fluorine gas producing solid magnesium fluoride. How much magnesium metal is required to produce exactly 50.0 grams of the magnesium fluoride product?

Exactly 100.0 grams of solid calcium oxide is combined with exactly 100.0 grams of solid diphosphorus pentoxide. This reaction produces solid calcium phosphate. Assuming 100% yield, how many grams of solid calcium phosphate will be produced?

i know this a lot please try to show work any help is appreciated

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
