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.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
