physical chem問題 plz help

[list=1][size=12pt]A waste containing 1 percent sulfuric acid (10,000 mg/L H[/size][size=8pt]2[/size][size=12pt]SO[/size][size=8pt]4[/size][size=12pt]) is neutralized by the [/size][size=12pt]addition of a concentrated lime slurry [made by dissolving Ca(OH)[/size][size=8pt]2(s) [/size][size=12pt]in water]. If the [/size][size=12pt]water temperature is 25°C before neutralization, what is it after neutralization? (hint: 1 [/size][size=12pt]calorie = the amount of energy needed to raise the temperature of 1 g of water by 1 °C and [/size][size=12pt]1 calorie = 4.184 Joule).[/size][*][/list]
