Outline a general method for the synthesis of each of the following polymers by radical polymerization. Show the monomers that you would use.
What are the pH, pOH, hydroxide ion concentration, and hydronium ion concentration of a 0.014-M diprotic acid solution?
A river contains 10.5 mg/L of dissolved silica. The measured pH = 6.5 and the water temperature is 25 degrees Celcius. Calculate the concentration of each silica species in solution.
What happens to the voltage of this cell as the cell is discharged? Why? a. Voltage increases b. Voltage remains the same c. Voltage decreases d. because product concentrations are increasing
The electophilic addition reaction of conjugated dienes that occurs at low temperatures and/or short reaction times is said to be under what? A)thermodynamic control B)kinetic control C)1,2-additon control D) 1,4-addition control
What is the partial pressure of oxygen gas in an oxygen and neon gas mixture at 1.280 atm. The gas mixture contains 15.00 g of oxygen and 15.00 g of neon
Complete and balance the following equations, and identify the oxidizing and reducing agents. (Recall that O atoms in hydrogen peroxide, H2O2, have an atypical oxidation state.)
one type of electromagnetic radiation has a frequency of 107.1 MHz another type has a wavelength of 2.12*10^-10m,and another type ofelectromagnetic radiation has photons with energy equal to 3.97*10^-19J/photon. identify each type of electromagnet..
Explain what is the PH of a solution prepared by dissolving 5.4g of lithium hydroxide in water to give 250ml of solution.
if you burn 10.00g of octane. if the temperature is 500K, and you have an expansion of 1.00 atm, how much work in joule can be done by the system if the octane is completely converted to CO2 and water vapor. what will be the enthalpy change
An ideal gas undergoes an expansion between 400K to 300K. However the path is chaotic, that is, not adiabatic, reversible, isothermal, at constant volume or pressure. Is the work positive, negative, zero, or not enough information and why?
You have a 10.40 g mixture of table sugar (C12H22O11) and table salt (NaCl). When this mixture is dissolved in 150. g of water, the freezing point is found to be -2.24°C. Calculate the percent by mass of sugar in the mixture.
One of the side effects of taking non-steroidal anti-inflammatories like aspirin and ibuprofen is a degradation of the integrity of the stomach lining.
