A student is preparing for an experiment in which she will react potassium hydroxide with sulfuric acid. She has 75.0 mL of sulfuric acid that contains 1.47 g H2SO4. How many grams of KOH does she need to completely react with the sulfuric acid?

a 85.7 g
b 1.68 g
c 0.420 g
d none of these

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?

Remember to use the proper number of significant figures and leading zeros in all calculations.gelatin has a density of 1.27 g/cm³. if you have a blob of gelatin dessert that fills a 2.0 liter bottle, what is its mass? 2540 g2500 g3.9 x 10-43.937x 10-4

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
