I'm not sure about how I'm supposed to find NaOH
concentration from a strong acid and strong base titration. I'm
thinking that 2.5×10^-8 mol per L that I calculated would make the
moles of NaOH 2.5x10^-8 mol since it's a one to one
ratio.

What is the heat of a reaction with a total reaction mixture volume of 70 5 mL if the reaction causes a temperature change of 6.4 °C in a calorimeter? Assume that the reaction mixture has a density of 1.00 p/ml. and a specific heat of 4.184 JigC The calorimeter has a heat capacity of 10.0 JC Answer What is the heat, q, in youles transfered by a chemcal reaction to the reservoir of a calorimeter containing 95.0g of dilute...

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...

In a coffee cup calorimeter, 50.0 mL of 1.00 M NaOH and 50.0 mL of 1.00 M HCl are mixed. Both solutions were originally at 24.6°C. After the reaction, the final temperature is 31.3°C. Given that the density of the NaCl solution is 1.038 g/mL and he specific of NaCl solution is 3.87 J/g-°C, calculate the ΔHneut/mole for the reaction of HCl with NaOH. Assume that no heat is lost to the surroundings. Part A. ) Why are the density...
