The coinage metals -- copper, silver, and gold -- crystallize in a cubic closest packed structure. Use the density of copper (8.95 g/cm3) and its molar mass (63.55 g/mol) to calculate an approximate atomic radius for copper.
What volume will 500 mL of gas at 20°C and a pressure of 420 mm Hg occupy if the temperature is reduced to -80°C and the pressure is increased to 650 mm Hg?
Draw the abbreviated structural formula of the products of the complete hydrolysis of lidocain.
What exactly is the reduction of alkynes? I just understand that it is a method for synthesizing alkenes. Why are the leaving groups for E2 reactions not as good as E1 reactions?
A system at equilibrium contains I2(g) at a pressure of 0.16 atm and I(g) at a pressure of 0.20 atm. The system is then compressed to half its volume
How much KClO3 in grams is needed to generate 7.50L of O2 at pressure of 1.00atm and temp of 298K?
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
Assume that sucrose is a molecular solid and does not ionize when it dissolves in water. Kf values are given here.
A copper refinery produces a copper ingot weighing 180lb . If the copper is drawn into wire whose diameter is 8.10 mm , how many feet of copper can be obtained from the ingot? The density of copper is 8.94g/cm3 .
You are asked to prepare 150 mL of a 0.059 M solution of silver nitrate. How many grams of silver nitrate do you need to weigh out.
63.0 mL of a 1.20 M solution is diluted to a volume of 208 mL. A 104-mL portion of that solution is diluted using 157 mL of water. What is the final concentration.
When an outside plastic envelope is removed, O2 molecules penetrate the paper causing the reaction to begin. A Typical packet contains 250 grams of iron to warm your hands or feet for up to 4 hours.
Ionization energy is the energy required to remove an electron from an atom in the gas phase. The ionization energy of lead is 715.0 kJ/mol.
