1. An impure sample of compound A is contaminated with two impurities B and C. The sample is to be purified by recrystallization using ethanol as the solvent. The solubility properties of the three components are summarized below. Solubility in Solubility in ethanol Solubility in 50 mL Solubility in 50 mL ethanol at -78 °C at - 0°C ethanol at -78 °C ethanol at - 0°C (g) (g) Compound A 0.12 g/mL 0.02 g/mL Impurity B 0.58 g/mL 0.04 g/mL Impurity C 0.005 g/mL 0.0003 g/mL The impure (7.5 g) sample contains 5.0 g of compound A, 1.5 g of B and 1.0 g of C and is recrystallized using 50 mL of ethanol. The sample is boiled with 50 mL of ethanol, filtered by gravity and then cooled in ice and filtered by suction. a) How much compound A should be obtained as the final product? Will the sample be contaminated with any of the impurities? Explain (using calculations to support your answer-fill in the missing masses in the table above).

Consider the following reaction in a sealed vessel kept at constant temperature: A(g) ⇌ 2B(g) If the reaction is started with 2.0 mol of A and no B, the amount of B at equilibrium is 3.0 mol. How many moles of A should one start with to obtain 6.0 mol of B at equilibrium under the same conditions (same vessel, same temperature, no gas B present initially)? A. 5.6 mol B. 5.0 mol C. 4.0 mol D. 6.0 mol E. 6.5 mol
Predict the product when the two substances mix. If the reaction occurs, write the balanced chemical equation. If the reaction does not happen, write "NA" A solution of nickel(III) nitrate is mixed with a solution of sodium hydroxide.
Now, let's use what we know about chemistry to infer how much acetic acid was in our sample. Let's look closely at the equation for the reaction we performed. HC2H3O2(aq) + NaHCO3(s) → NaC2H3O2(aq) + H2O(1) + CO2(g) Based on this balanced chemical reaction, we can see that for every one mole of CO2 that was produced one mole of acetic acid was consumed. Based on this, calculate the moles of acetic acid and grams of acetic acid that must have reacted in each sample. Sample Data for Vinegar Lab moles CO2 Produced Moles HC2H3O2 Consumed g HC2H302 Consumed by by Reaction by Reaction Reaction -2 g NaHCO3 0.0329 -4 g NaHCO3 0.0464 -6 g NaHCO3 0.0523 -8 g NaHCOз 0.0477 -10 g NaHCO3 0.0489
