1. Based on the student data, the prediction was correct. Remember, heat is the transfer of energy from the high temperature object to the low temperature object until equilibrium is met and that was what happened in this case. How did this transfer of energy occur at the molecular level? A) Heat is transferred from one object to another object through particle collisions. The hot water had the greatest kinetic energy. Particle collisions transferred that energy from the hot water, to the can, and then to the cooler water. B) Temperature changes due the transfer of heat energy. The hot water had the greatest heat energy. Heat was transferred from the inside of the can to the outside of the can, or into the water held in the styrofoam cup. C) Heat energy always travels from high to low. The heat energy flowed through the water in the can, through the metal since it is a good conductor, and then out into the cooler water, raising the temperature there. D) Because the hot water had the highest temperature, it also had the greatest stored or potential energy. That energy was shared with the cooler water until the two volumes were at the same temperature.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

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
