Draw the structure of a hydrocarbon that reacts w/ 2 equivalent of H2 (H sub 2) on catalytic hydrogenation and gives only succinic acidon reactions with acidic KMnO4 (KMnO sub 4).
An acid-base neutralization reaction is exothermic. For the measurement of the enthalpy of neutralization, the change in Hn(n is suppose to be a subscript), for the reaction, heat is inevitably lost to the calorimeter (beaker or styrofoam cup).
Maleic acid is used to retard the breakdown of fats. Imagine that you prepared a buffer by adding 14.35 millimoles of maleic acid and 20.57 millimoles of sodium hydrogen maleate to a 250.0mL volumetric flask
Using a sample of 0.385 g of Alka-Seltzer, the mass of Carbon dioxide is found to be 0.122 gram. Compute and enter response (in numerical value only) to three significant figures.
the order of the reaction was n=0 and the value of the rate constant was 3.41*10^-3 M s^-1. I could find the order of reaction and the value of the rate constant but I am clueless about how to find the rate of reaction when [A]=0.15M.
bathed by an atmosphere of nitrogen at 77K and 1 bar? Assume every nitrogen molecule that strikes the surface sticks and that a nitrogen molecule covers an area of 1.1e^5 pm^2.
This time took a one-hour break after adding the acetic anhydride but before adding the sodium acetate solution. The student obtained no product. Explain, with chemical equations and/or formulas, what went wrong.?
The freezing point of benzene is 5.5oC. What is the freezing point of a solution of 5.00 g naphthalene (C10H8) in 444 g of benzene (Kf = 4.90oC/m)
How many grams of solute are needed to prepare the following solutions? 1. 135.0mL of 22% (w/v) glucose (C6H12O6) 2. 60mL of 4.6% (w/v) (KCl)
How long will it take to deposit 0.00470 moles of gold by electrolysis of KAuCl4 (aq) using a current of 0.214 amperes? Which metal would be suitable to provide cathodic protection from corrosion for an iron bridge?
The electronegativty for both sulfur and carbon is 2.5. Therefore the compound CS2 would be expected to A) be ionic with C as the anion
How many moles of H+ are in 1.000 mL of the aqueous 2.500 molar HCl solution mentioned above? What is the normality of solution mentioned above? How many H+ ions are present in 1.000 mL of this solution?
Calculate the pH at the points in the titration of 40.00 mL of 0.425 M NH3 for the reaction below. NH3(aq) + HNO3 -> NH4+(aq) + NO3(aq) For NH3, Kb = 1.8x10-5. Enter your answer with 2 decimal places. Enter scientific notation as 1.23E4. (a) When ..
