a. write a balanced chemical equation for the above reaction.

b. show by unit conversion (show conversion factors, ie. 2 g h20 x 1 mole h2o/18 g h2o x x = answer?

Agas occupies 475 cm^3 at 313k. find its volume at 367k. you must show all of your work to receive credit. be sure to identify which of the gas laws you will be using

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.

How do you know when a chemical reaction has occurred
