Nickel has a face-centered cubic unit cell. If the density of Nickel is 6.84 g/cm3. Compute a value for the atomic radius of nickel
Fundamentals of chemistry - The conditions under which gases behave most ideally and Under the Bronsted?Lowry definition a base
what mass of aspirin can be prepared by reacting 5.00 g if salicylic acid with an excess of acetic
Based on the sign of E°cell, classify these reactions as spontaneous or nonspontaneous as written. Assume standard conditions. Al3+(aq) + 3Na(s) ---->Al(s) +3Na+(aq) 3Fe2+(aq)+2Cr(s)---->3Fe(s)+2Cr3+(aq) Zn2+(aq) + Sn(s)---->Zn(s) + Sn2+(aq)
Propane gas (C3H8) is used as a fuel in rural areas. How many liters of C02are formed at STP by the complete combustion of the propane in a container with a volume of 15.0 L
If 20.0 dm3 of methane, CH4, react with 200.0 dm3 of air at STP, calculate the dm3 of carbon dioxide gas produced.
draw all three resonance structures for the carbocation intermediate that results from STEP 2 in the electrophilic aromatic substitution reaction when benzoic acid reacts with Br2 in the presence of FeBr3
Commercial electrolytic cells for producing aluminum operate at 5 volts and 100,000 Amperes. How long does it take to produce 1000 kilograms of aluminum
Define why the atomic mass of copper is not exactly equal to 64, midway between the mass numbers of copper-63 and copper-65.
When a 2.691 g sample of the unknown organic compound is vaporized at 90.0(degrees)C and 708. mmHg it is found to occupy a volume of 1.00L.
The Kow for carbon tetrachloride is 220. Using the rule of thumb that log(Koc) = .8*log(Kow), and assuming an organic carbon content of 1% you can estimate the retardation factor for carbon tetrachloride.
A. When dissolved solute and undissolved solute exist in equilibrium with each other in a solution, that solution is said to be "supersaturated".
What is the pH of a dilute 0.00336 M solution of formic acid? Formic acid is monoprotic with a Ka of 1.70 x 10-4. You should use the quadratic equation for this one because the solution is very dilute.
