What is the pH of the solution created by combining 2.00 mL of the 0.10 M base with 8.00 mL of the 0.10 M acid
What is the balanced net ionic equation for precipitation of CaCO3 when aqueous solutions of Na2CO3 and CaCl2 are mixed
If the river flows at an average rate of 0.455 cubic feet per second. what is the additional concentration of nitrogen (expressed in milligrams of nitrogen per liter) in the river water due to the farmer's fertilizer?
Determine the final temperature achieved in this expansion, and the corresponding work done by the gas for the cases that it is 1) Helium, 2) Krypton.
The water at the gas-collecting port is assumed to be 25 degrees C, but it is actually 15 degrees C. How will this error affect the reported mass of aluminum in the sample
Write the reaction mechanism (using arrows) of 6-ketoheptanal + NaOH to form the product 1-cylclopentyl methyl ketone. What type of reaction is this?
A 21.0-mL sample of an unknown H3PO$ solution is titrated with a 0.100M NaOH solution. The equivalence point is reached when 18.35mL of NaOH solution is added.

Calculate the vapor pressure of water above a solution prepared by adding 23.5 g of lactose (C12H22O11)to 200.0g of water at 338K . (Vapor-pressure of water at 338K 187.5 torr.)
The Ksp for BaF2 is 2.4 x 10-5. When 10 mL of 0.01 M NaF is mixed with 10 mL of 0.01 M Ba(NO3)2, will a precipitate form
Some investigators modified the Cys 278 with iodoacetamide and found that the enzyme activity was abolished as a result. They concluded that the Cys 278 residue was absolutely essential for enzymatic activity. But other investigators modified the ..
A 7.75-L container holds a mixture of two gases at 37 °C. The partial pressures of gas A and gas B, respectively, are 0.209 atm and 0.735 atm. If 0.130 mol a third gas is added with no change in volume or temperature, what will the total pressure ..
