Doc Inmaking does a titration using sodium hydroxide (NaOH) and sulfuric acid (H2SO4). He pipets 20.00 mL of H2SO4 solution into the Erlenmeyer flask and adds two drops of phenolphthalein. He does the titration using 0.5000 M NaOH. The initial buret reading is 0.70 mL and the final buret reading is 35.23 mL. Write the balanced chemical equation for sodium hydroxide reacting with sulfuric acid to produce sodium sulfate and water. Determine the mole ratio between the acid and the base. (Hint: it is not one-to-one.) Then calculate the molarity of the sulfuric acid (H2SO4) solution. Enter the H2SO4 concentration with 4 significant digits and units of mol/L.

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
