A student is preparing for an experiment in which she will react potassium hydroxide with sulfuric acid according to the equation shown below. 2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

She has 75 mL of sulfuric acid solution that contains 1.47 g of sulfuric acid. How many grams of potassium hydroxide does she need to react completely with the sulfuric acid?

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.
