3. Beaker A (Heat Meter) tells us how much heat energy left the hot plate and entered into Experiment Beaker C. One calorie of energy
is the amount of heat required to increase the temperature of 1 ml
of water 1°C. How much did the temperature change in Beaker A?
°C. (Subtract the starting temperature if it was above 0°C.)
4. Now, calculate the total calories of heat recorded by the Heat Meter
(Beaker A) considering both the amount of water in it and the
temperature change of the water.
calories
5. The answer to question #4 is the amount of energy to vaporize 10 ml
of water in Beaker C. How many calories would be required to
evaporate only 1 ml of water?
calories
6. Based on your results, discuss how effective is the evaporation of
water at removing excess heat from your body (sweating).

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

In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al oxidizing agent = reducing agent =

The atomic number, or number, is the described as the number of in the nucleus of an chemical element.
