Light in a vacuum travels at a speed of 3.00x10^8 m s^-1. Pluto's average distance from the sun is 3.6 billon miles. How many minutes does it take sunlight to reach Pluto
At 25C, H2O2 decomposes according to the following equation. 2H2O2(aq) => 2H2O (l) + O2(g) .55V
Partition coefficient in octanol, A monoprotic acid with a Ka of 2.83 x 10-5 has a partition coefficient of 2.8 (favoring octanol) when distributed between water and octanol.
Calculate the potential developed bya voltaic cell using the following reaction if all dissolved species
How many grams of glucose (C6H12O6) must be dissolved in 563 gram of ethanol (C2H5OH) to prepare a 2.40 x 10-2 m solution?
What is the pH of the resulting solution when 25 mL of 0.10 M NaOH is added to 25 mL of 0.25 M HNO3?
it took 35.40mL of 0.100 M NaOH to titrate a 2.55 gram of a weak acid to the equivalence point. The pH when 17.7mL of the NaOH had been added was 6.2. What was the Ka for the acid
calculate the weight of sodium hypochlorite, NaOCl.
Draw a detailed mechanism for the FeBr3-catalyzed reaction of the ethylbenzene with bromine, and show why the sigma complex (and the transition state leading to it) is lower in energy for substitution at the ortho and para position than it is for ..
Commensurate with the quantities of chemicals involved. Choose a distillation flask, which will be approximately half filled by the quantity of liquid you have to distil
The Henry's law constant for helium gas in water at 30°C is 3.7 10-4 M/atm; that for N2 at 30°C is 6.0 10-4 M/atm. If the two gases are each present at 1.2 atm pressure, calculate the solubility of each gas. What is the Molarity of He and N2
