(b) Determining enthalpy change for the reaction between NaHCO3 and H2SO4, AH31. Empty and rinse the styrofoam cup used in (a), and place the cup back in the250 cm3 beaker.2. Using the same measuring cylinder used in (a), place 40 cm3 of FA 3 into the styrofoam cup.3. Wash an...
H2SO4+ Na2S2O3= Na2SO4+ SO2+ S + H2O. Enter the amount of any of the substances to determine the ideal amounts to maximize the theoretical yield of the reaction. To find the limiting and excess reagents when a non-ideal amount of each substance is used, you can ...
Additions of HCI, NaCl, H2SO4 and Na2SO4 to dilute HNO3 reduce the dissolution rate of Fe. The effect produced by the salts exceeds that of the acids. In contrast to its action in dilute solutions, the Clion induces pitting corrosion in concentrated HNO3. The attack starts after an ...
Which of the following salts is produced during the neutralization reaction between sodium hydroxide and hydrochloric acid? a. NaCl b. Na2H4 c. Cl(NO3)2 d. H2NO3 e. HNO4 Identify if the following are acid or a base: a. H_2SO b. Sr(OH)_2(aq) c. HB...
How many grams of sodium sulfate will be formed if you start with 300 grams of sodium hydroxide and you have an excess of sulfuric acid? 2NaOH + H2SO4 arrow 2H2O + Na2SO4 What is the molar ratio between sodium sul...

H2SO4 E1 (alcohol w/ triangle wedge structure) - the structure unfolds- the wedge/dash goes away- a double bond forms between the carbon that had the wedge/dash and goes towards the opposite end of where the triangle was- OH goes on the end where the triangle was HO- E2 (alcohol w...
Draw the product of the reaction between 2−pentanol and K2Cr2O7, H2SO4, H2O, heat. Distillation: When heating alcohols to react with K2Cr2O7, H2SO4,&H2O, we generally use a distillation apparatus so that we can isolate the product. In these reactions, the...
