### 8.99 in Sixth Edition

How would we go about finding the final temperature of HCl if the initial temperature is 25 degrees Celsius? What do you do with the volume and molarity you are given?

To find out the final temperature, you should start out by writing the chemical equation and figuring out which is the limiting reactant (that's what the molarity values are for).

After finding out the limiting reactant, you can then find the enthalpy of reaction (delta H) and multiply that by the number of moles to determine the amount of energy released.

From there, just plug in the values to the equation delta h = moles x specific heat x delta T, and solve for delta T.
