You are performing an experiment where you place 6.7797 g of Al metal at 205.24 equationC into a coffee cup calorimeter that contains 87.4 g of water at 25.37 equationC. The final temperature of the water in the coffee cup is 28.67 equationC. Remember, the heat gained by the water is equal to the heat lost by the Al. equation What is the specific heat (C) of the Al in J/g°C? Cwater= 4.184 J/g°C. Do not include units. If you need to express your answer as an exponential number, use this template: 1445 should be typed as 1.445e+003

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
