A 0. 750 g sample of a compound that might be iron(ii) chloride, nickel(ii) chloride, or zinc chloride is dissolved in water, and 22. 40 ml of 0. 515 m agno3 is required to completely precipitate all the chloride ion as silver chloride. What is the compound?

How many molecules of sucrose c12h22o11 are there in 454 grams of sucrose

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
