The chemical reaction shown below is carried out in a coffee cup calorimeter. A student mixes 10.0 mL of 0.100 M H2A(aq) and 20 mL of 0.100 M NaOH(aq), both initially at 25 °C. The student records the highest temperature of 40. °C for the reaction. a) What indicates that this is an acid-base reaction? Explain your answer. b) Determine the amount of energy involved in the reaction in the coffee cup calorimeter. The density of the resulting solution is 1.00 g/mL and has the same specific heat capacity as water, 4.2 J/g °C. c) Determine the enthalpy of the reaction, in kJ/mol rxn.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
