Show step-by-step mechanisms to produce the indicated polymeric substrate products. include an appropriate termination step where needed.
1. polypropylene as major substrate prod, using propene monomers
2. poly (propylene) glycol as major substrate prod, using appropriate ether monomers.
4.5 L of Mg(OH)2 solution was titrated with 5.03 mL of 0.200 M HCl. Calculate the the molarity of Mg(OH)2 solution and the ksp.
We find coesite and stishovite in shocked Coconino Sandstone at meteor Crater. We infer that coesite and stishovite formed from the transformation of quartz at high pressure and temperature.
What is the density of lead if a rectangular bar measuring 0.500 in height, 1.55 in width, and 25.00 in length has a mass of 220.9g.
A carbonated beverage is made by saturating water with carbon dioxide at 0 C and a pressure of 3.0 atm. The bottle is then opened at room temperature (25 C), and comes to equilibrium with air in the room containing carbon dioxide CO2(PCO2=3.4x10?4..
is independent of pressure. By doing so, obtain an expression for V as a function of T and ? at fixed P.
Draw an absorption spectrum of leucoindigo. What color is absorbed by leucoindigo? Draw a simple energy level diagram of leucoindigo. Calculate the energy difference between energy levels.
Solid iron(III) oxide reacts with solid aluminum to produce solid iron and solid aluminum oxide. If 50.0 grams of iron(III) oxide were mixed with 50.0 grams of aluminum, what maximum mass of iron metal could be produced?
What is the pH of this buffer solution? (Neglect the volume change that occurs with addition of solid sodium nitrite) b.) Calculate the pH when 2.00 mL of 0.0275 M NaOH are added to 50.0 mL of buffer solution.
how do you find the specific heat of platinum if 23.6 grams is heated from 10.0c to 20.0c using 30.68 J of heat.
