To find the concentration of bleach, you will need to
back-calculate from the amounts of other reagents used.
If 9.8ml of 0.36M sodium thiosulfate were used in the titration,
calculate
A. Moles of KI3 generated
B. Moles of KI
C. Moles HOCl
D. Moles of NaOCl
Mass percent is defined as: mass % = mass of NaOCl/Mass of
bleach solution x 100%
If you know the mass % of bleach is 4.5%, then what mass of
active ingredient do you...
What are some ways you might measure the concentration of an
unknown copper solution? (Other than using a voltmeter). Discuss
the advantages and/or disadvantages of using the concentration
cell.
You were given 25.00mL of an acetic acid solution of unknown
concentration. You find that it requires 37.15mL of a 0.1047M NaOH
solution to exactly neutralize this sample (phenolphthalein was
used as an indicator). Show detailed work.
Explain what differentiates one type of cell from another
(morphology aside) at the molecular level? What role does DNA play
in this differentiation process?
The most efficient way to send a spacecraft from the earth to
another planet is by using a Hohmann transfer orbit (the
figure (Figure 1)). If the orbits of the departure and destination
planets are circular, the Hohmann transfer orbit is an elliptical
orbit whose perihelion and aphelion are tangent to the orbits of
the two planets. The rockets are fired briefly at the departure
planet to put the spacecraft into the transfer orbit; the
spacecraft then coasts until it...
Aside from potential financial losses, what are two other
negative impacts an identity theft victim might encounter? What
steps should you take if you become a victim of identity theft?
