Initially a NaOH solution was standardized by titration with a sample of potassium hydrogenphthalate, KHC8H4O4, a monoprotic acid often used as a primary standard. A sample of pureKHC8H4O4 weighing 1.518 grams was dissolved in water and titrated with the NaOH solution. Toreach the equivalence point, 26.90 milliliters of base was required. Calculate the molarity of theNaOH solution. (Molecular weight: KHC8H4O4 = 204.2)

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

What statement goes against the kinetic theory of gases

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.
