A chemist working for a super glue company is asked to find a way to speed up a 3 component reaction used in the manufacturing process. The general reaction can be written as aA + bB + cC → dD where product D is the super glue. The chemist performs the reaction and measures the concentration of chemical A as time passes. Plotting the obtained data produces the following graphs:
If the initial concentration of A is 1.0 M, what is the value of k? *Use correct units and write exponents as unit^-# if necessary.
Ca2+ in a drinking water sample was analyzed by the following reactions below:
Ca2+(aq) + C2O42-(aq) → CaC2O4 (s) → CaO(s) + CO(g)+ CO2(g)
First an excess of C2O42- was added to 0.10 L of the Ca2+ water sample.
Then CaC2O4 was precipitated, which was demcomposed into CaO with filtering and some heat.
The CaO was measured to be 5.61 mg.
What is the concentration of Ca2+ in the original water sample? The MW of CaO is 56.1 g/mol.

- Q) Drinking water may contain several unwanted ions such as phosphate ions. In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed. The reaction for this process is below: 5 Ca(OH)2 (aq) + PO43- (aq) → Ca5OH(PO4)3 (s) + OH- (aq) a) If 3.00 mL of 0.100 M calcium hydroxide is mixed with 4.00 mL of an aqueous solution of 0.0800 M phosphate ions (PO43-).
