Method
Follow these steps and then answer the questions.
1
Half-fill a beaker with crushed ice and measure the temperature.
2 Set up the apparatus as shown in the diagram.
3 Gently heat the beaker using a Bunsen burner.
While stirring continuously, measure the temperature every 10 seconds.
Continue until the water has boiled for a few minutes.
5 Present your results in a neatly drawn table.
6 Plot the heating curve of water, placing temperature (in °C) on the vertical
axis and time (in minutes) on the horizontal axis.
7 Determine the cooling curve of water by starting your measurements at the
boiling point of water.

Questions
a) At what temperature does heating not result in a temperature rise?​

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

Can someone me with 3 and 4 plz. this is for masteries test.
