Explain how society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water. Compare and contrast the accuracy and precision of at least three types of measurements used in your life
Calculate the CO3- concentration of a 5.45 x 10-4 M H2CO3 (carbonic acid) solution. Ka1 and Ka2 of carbonic acid are 4.3 x 10-7 and 4.8 x 10-11 respectively.
a 3.25 g sample of solid calcium carbide reacted with water to produce acetylene gas and aqueaous calcium hydroxide. it
Calculate the pH for a mixture of .050 M formic acid (HCO2) and .050 M hypochlorous acid (HClO)
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..

A chemist was studying the solubility of two "new" compounds she made in her laboratory at work; NI3 and CBr4. They will not dissolve in each other Explain why they may not be dissolving in each other, based on molecular comparison, and draw the 3..
Find the pH and the concentration of each of the species of lysine in a solution of .010M lysine monohydrochloride (lysine-HCl)
what is the percent Zn in the mixture? (At the same temperature and pressure, the Mg/HCl reaction gave 24.2 L gas/mol Mg.)
The rate constant for the equation 2C2F4 --> C4F8 is 0.0438 M?1· s?1. We start with 0.142 mol C2F4 in a 5.00-liter container, with no C4F8 initially present. What will be the concentration of C2F4 after 1.00 hour
