Green color is usually made by combining blue and yellow. Does the green color of M&M uses the same yellow and blue dyes as the yellow M&M and blue M&M? How do can you tell from your experiment?
The addition of anhydrous calcium chloride to the crude product obtained from the separation procedure often results in the product becoming clear (transparent). What causes the clearing?
State a balanced equation for the reaction of aqueous sodium carbonate with aqueous nitric acid to yield CO2, NaNO3, and H2O.
Assume the yield of the reaction is 100 percent. Assume the volume, temperature, moles, and presure are actually known to three signficant figures.
Given the following boiling point data, which one of the liquids would you expect to have the HIGHEST vapor pressure at room temperature
Compute the solubility of silver sulfite, Ag 2 SO 3 in units of grams per liter and complete and balance these given redox equations by the half reactions method (the oxidation reaction and the reduction reaction)
For the equalibrium PCl5(g) PCl3(g) + Cl2(g), Kc= 2.0 x 10^1 at240 celcius. If pure PCl5 is placed in a 1.00-l container and allowed to come to equalibrium, and the equalibrium concentration of PCl3(g) is 0.23 M, what is the equalibrium concentr..
Estimate the temperature at which calcium carbonate is likely to decomp under 1atm of pressure. Reaction: CaCO3(s) -> CaO(s) + CO2 (g) For this rxn: dHstandard = 177.8 kJ and dS standard= 160.5 J/K (notice unit differences)
a pure rock sample believed to be pure calcium carbonate is subjected to chemical analysis and found to contain 51.3
You weigh 10 of the rings as well as find that they have combined mass of 7.38g; you then place them Ina graduated cylinder 2.5 cm in diameter as well as observe that the water level rises by 8.45 mm. Are the rings pure silver
When one equivalent of ethylmagnesium bromide is treated with one equivalent of 5-hydroxy-2-pentanone. Does addition of two equivalents of the grignard reagent to this ketone yield a different product(s)? If so, give the structure (s).
In at least 300 to 400 words,describe the elements of the Integrated Solid Waste Management program. Give a detailed discussion and explanation.
You find a reagent bottle that is labeled with "vanadium (III) nitrate hydrate" and it contains a chalky looking powder. Do you believe the label? Why or why not?
