7. A 100 ml sample of 0.100 M NaOH was reacted with 100 ml of 0.100 M HCl in a
coffee-cup calorimeter with lid by the following reaction:
HCI (aq)
+
NaOH (aq)
->
NaCl (aq)
+
H20 (aq)
If the temperature of the water and the calorimeter (heat capacity of calorimeter =
200 J/°K) increases from 25.00 °C to 25.97°C, (1) what is the AH of the reaction?
Using the definitions at the beginning of the module describe (2) the calorimeter +
contents, (3) the type of process.

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.
