AI Generated Solution

To find the heat of neutralization of dichloroacetic acid (CHCl₂COOH) by ammonium hydroxide (NH₄OH), we can use the given heats of neutralization for the other reactions and apply Hess's law. ### Given Data: 1. Heat of neutralization of CHCl₂COOH by NaOH = 12830 cal 2. Heat of neutralization of HCl by NaOH = 13680 cal 3. Heat of neutralization of NH₄OH by HCl = 12270 cal ### Step 1: Write the reactions ...
