The compounds kno3 and nano3 are soluble in water.
55 compare the entropy of 30. grams of solid kno3 at 20.°c with the entropy of 30. grams of kno3 dissolved in 100. grams of water at 20.°c. [1]
56 explain why the total thermal energy of a sample containing 22.2 grams of nano3 dissolved in 200. grams of water at 20.°c is greater than the total thermal energy of a sample containing 11.1 grams of nano3 dissolved in 100. grams of water at 20.°c. [1]
57 compare the boiling point of a nano3 solution at standard pressure to the boiling point of water at standard pressure. [1]

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
