Write the correct equation for the ready formation of a metallic deposit on placing a Ni(s) strip into 0.1 M copper nitrate.
calculate how many pounds of carbon dioxide are produced when 40.00 gallons of gasoline are combusted. Assume that the primary ingredient in gasoline is octane, C8H18(l), which has a density of 0.703 g·mL-1
What is the rate constant for the reaction at 85°C?
The greater volume per mole at the higher temperature indicates greater average intermolecular distances and hence weaker intermolecular forces.
A 19.91 g sample of Mo2O3(s) is converted completely to another molybdenum oxide by adding oxygen.
We can measure the concentration of HCl solution by reaction with pure sodium carbonate: 2H^+ +Na_2CO_3 -->2Na^+ +H_2O + CO_2. Complete reaction with 0.9674 + and - 0.0009g of Na_2CO_3 (FM 105.9884 + and - 0.0007) required 27.35 + and - 0.04 mL of..
A balloon filled with helium gas at 20C occupies 2.91 L at 1.00 atm. The balloon is immersed in liquid nitrogen at -196C, raising the pressure to 5.20 atm.
A 43 kg person drinks 450. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 17% of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake.
The quantity of atmoshperic SO2 (g) can be determined by reaction with H2O2 (aq), according to the balanced chemical equation...
Comment on the following observation: in its complexes, Co(III) forms strong bonds to O- and N- donor ligands, moderately strong bonds to P- donor ligands
So he used this in his calculation. Actually it boiled at 102.*c during experiment. Did this assumption cause his calculated specific heat to be too high, too low or not affect?
An interstitial alloy prepared from two metals. metal A with the larger atomic radius has a hexagonal closed-packed structure. What if the formula(for example:A2B,AB,AB2)of the alloy if atoms of metal B occupy the following?
Determine which metal will reach the lowest temperature If the same amount of heat is added to both the metals?
