Starting with a 30% (w/w) solution of hydrogen peroxide, how many mL would you need to dilute in order to end up with 25.00mL of a 3.6 M hydrogen peroxide solution? What are the hazards and safety precautions associated with 30% hydrogen peroxide. Assume a solution density of 1.11 g/mL.

This question is about concentration measurements and its effect on E and K.

Cu/Cu^+2 // Ag/Ag^+2

It's same voltaic cell setup directions but for different concetrations of Ag+2 solutions: 0.2M, 0.02M, 0.0020M and 0.00020M.

Calculate the E of the above different Ag+2 solution by using this form of the Nernst equation: E= E⁰ - (0.0257/n)*lnK where K is the qulilbrium constant and n is the number of electrons and E⁰ is standerd cell pontential at STP

Please show the process and explains. Thank you

Explain, in detail, why atomic radii do not increase uniformly with increasing atomic number. Give specific examples in your answer.

A sample of butane gas, C4H10, was slowly heated at constant pressure of .80 bar. The volume of the gas was measured a series of different temperatures and plot of volume vs. temperature was constructed. The slope of the line was .0208 L/K. What was the mass of the sample of butane? Please explain.

A 55.0 mL solution of 0.126 M potassium alaninate (H2NC2H5CO2K) is titrated with 0.126 M HCl. The pKa values for the amino acid alanine are 2.344 (pKa1) and 9.868 (pKa2), which correspond to the carboxylic acid and amino groups, respectively. a) how do you calculate the PH of the first equivalent and b) the second equivalent? please help
