Experiment for ideas on possible products for this read 4. The O'Keefe's have 50 gallons of cucumbers for pickling. The 1.5 M KOH solution costs $4.50 per liter, 9 M
H2SO4 solution costs $8 per liter, and ethanol costs $20 per liter. A 50 g jar of alum from the grocery store costs
$8.59. Do you think it's worth the time and trouble for Richard and Diane to make their own alum from
discarded aluminum cans? Explain your answer showing all calculations.
ribute toward lowering the nercent yield of alum.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
