If 29.7 mL of 0.0205 M KOH us required to completely neutralize 25.0 mL of a HC2H30 solution. What is the molarity of the acetic acid solution?
HC2H3O2 + KOH ---> KC2H3O2 + H2O
determine the initial concentration - Constant rate is 3.20×10-4 M/s for a zero-order reaction. concentration has dropped to 9.00×10-2 M after 60.0 seconds
Karel added 45.5 mL of 1.1 M HCl to his; and Caleb added 50.0 mL of 1.0 M HCl. Two of these students will report, within experimental error, the same increase in solution temperature for the neutralization. Which are the two students? Explain.
in other words, why isn't the tetra-alkylated ortri-alkylated product formed? What are the two other isomers (structure and name) that are possible of forming?
What are the spectator ions in the solution after the complete neutralization reaction occurs when mixing the strong base NaOH
Consider the oxidation of sodium metal to sodium oxide described by the balanced equation
The flask was then shaken until the solution was uniform. A 45.0- sample of this glucose solution was diluted to 0.500 . How many grams of glucose are in 100. of the final solution?
A beaker with 100 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.60 mL of a 0.380 HCl solution to the beaker. How much will the pH c..
How many moles of NaOH should be added to a solution containing 0.440 moles of formic acid, HCOOH, to prepare a formic acid/formate
Joseph Priestley discovered oxygen in the eighteenth century by using heat to decompose mercury(II) oxide: 2 HgO(s) + heat --> 2 Hg(s) + O2(g)
In the reaction below, 6.31 atm each of Br2 and I2 were placed into a 1.00 L flask and allowed to react: Br2(g) + I2(g) 2 IBr(g) Given that Kc = 80.8, calculate the equilibrium pressure of IBr.
Propanol freezes at -89.5 degrees C and boils at 82.3 degrees C. What quantity of heat is needed to convert 10.0 g of solid 2-propanol at -89.5 degrees C to a vapor at 82.3 degrees C?
At what temperature would a 1.80 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 degrees C/m. answer in degrees C
