If heat is given off in the reaction of the acid and base where do you think the energy is coming from?
a. The friction from the vigorous mixing and stirring action of the student
b. The acid dissociation
c. The net energy released from the breaking and formation of chemical bonds in the solvent water
d. The net energy released from the breaking of chemical bonds in the reactants and formation of chemical bonds products

3) You would like to measure the heat of neutralization of an acid with a base. You mix 225 mL each of 0.65 M HNO, and 0.65 M LiOH, both at a temperature of 18.1 °C in a calorimeter cup equilibrated to that same temperature. After following the temperature change for 10 min and extrapolating it back to the time of addition, you find that the "final temperature" after mixing was 22.3 °C. Previously, you measured the heat capacity of...

The net-ionic equation for an acid base reaction involves transfer of a proton (H ion) from the acid to the base. The products represent the conjugate base and acid of the reacting acid and base. The net-ionic equation for this system is shown here. HF-CN= F-HCN If you compare two acids and one is stronger than the other, how do the strengths of their conjugate bases compare? It is given that HF is the stronger acid. Which is the stronger...

A calorimetry investigation is performed to determine the heat of neutralization when hydrochloric acid and sodium hydroxide solutions are mixed. Write the complete chemical equation for the reaction between hydrochloric acid and sodium hydroxide. Write the net ionic equation for the reaction between hydrochloric acid and sodium hydroxide. The procedure then calls for measuring 50.00 mL of each 0.10 molar solution. Why is it important to measure the volumes as accurately as possible? What is the most accurate measuring instrument...

Run 2 B, all questions, please help me, thank you very much
A chemical reaction involves breaking, making, or changing chemical bonds. These alterations in bonding lead to a change in enthalpy, AHo, between the products and reactants. This enthalpy change takes into account the change in intermal energy in the system and the work done by the system on its surroundings during the reaction. If the reaction occurs at a...

Lab 9 Heat of Reaction
OBJECTIVE:
To experimentally determine the heat of reaction for two
exothermic reactions.
DISCUSSION:
The heat given off or gained in a reaction is called the heat
of reaction (∆?????????).
A reaction that releases heat is known as an exothermic
reaction; an endothermic reaction
is one that absorbs heat.
The heat of the reaction corresponds to one mole of the
reactant and is expressed in
kilocalories per mole of reactant or in kilojoules per mole of...

Problem 9.10 Trimethylpentane The standard heat of combustion (AH) of liquid 2,3,3-trimethylpentane (CgH18) is reported in a table of physical properties to be - 4850.0 kJ/mol. A footnote indicates that the reference temperature for the reported value is 25°C and the presumed combustion products are CO2(g) and H20(9). The heat capacity of water is approximately 75.40 J/(mol K) over the temperature range of interest.
