A student followed the procedure in this experiment, using 48.60 mL of 0.977 molar HCl and 51.10 mL of 0.977 molar NaOH. Analysis of the collected data resulted in a heat transfer of 2770 J during reaction. Use this information to determine the heat of neutralization for this reaction in kJ/mol. Give your answer in in decimal format.

A 25.0-g sample of garden compost was analyzed for chloride content. The sample was dissolved in water, and the chloride was precipitated as silver chloride. 1.58 g of dried precipitate was obtained. Calculate the mass percent of chloride in the sample.

A flask contains 4.00 g of solid sodium hydroxide . Some water is added to the flask to dissolve the sodium hydroxide , and enough water is added to fill the flask to a volume of 50.0 mL . What volume of 1.00 M is needed to neutralize the sodium hydroxide ?

Suppose you added 40 mL of water to your vinegar sample instead of 20 mL. Would the titration have required more, less or the same amount of NaOH(aq) for a complete reaction? Explain.

Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients. A precipitate forms when aqueous solutions of copper(II) iodide and potassium hydroxide are combined. (Use the lowest possible coefficients. Omit states of matter.) + +

Solubility is the ability to dissolve certain substances(solutes) into a solvent. You are a student in Mrs. Bateast's Chemistry class and you were given the assignment to compare solubilities of salt in different solvents at different temperatures. You added salt at a consistent rate and amount until you reached the point of full saturation. The amount added to each solvent at saturation was recorded. The results of the experiment are shown in the tables: Table 1: 20 °C Mass of Salt at Saturation 43 g 38 g 0.01 g 3 g Solvent Water Ethanol Hexane Dichloromethane Table 2: 35 °C Solvent Water Ethanol Mass of Salt at Saturation 52 g 45 g 0.02 g 4g Нехane Dichloromethane Using CER and your knowledge from data listed above, if the temperature of ethanol solution increased by an additional 10 degrees, what would happen? Construct a line graph is required as well.

When aqueous solutions of iron(II) nitrate and sodium phosphate are combined, solid iron(II) phosphate and a solution of sodium nitrate are formed. Write the net ionic equation for this reaction. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)
