When comparing two gases to determine which one is closest to an ideal gas, which strategy is best? a. look up the van der waals' contstants. the gas with the smaller "b" value must be more ideal

b. calculate r. the more ideal gas is the one with an r value closest 0.08206 l • atm • mol–1 • k–1

c. look up the van der waals' contstants. the gas with the higher "a" value must be more ideal.

d. calculate the molar mass of each gas. a large molar mass indicates an ideal gas.

Which of the following is not a true statement about dwarf planets? a the kuiper belt contains comets, asteroids, and dwarf planets. b ceres is a dwarf planet located in the kuiper belt. c the largest known dwarf planet in the solar system is named eris.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients
