1. A 1.2048 g sample of impure Na2CO3 is dissolved and allowed to react with a solution of CaCl2. The resulting CaCO3, after precipitation, filtration, and drying, was found to weigh 1.0362 g. Assuming that the impurities do not contribute to the weight of the precipitate, calculate the percent purity (mass percent) of the Na2CO3. yields The equation for the reaction is Na₂CO₂ +CaCl, CaCO₂ + 2NaCl. 19.80 91.08 18.90 81.09

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. [[] → BaCl₂(aq) + H₂O(1) X S
Standard airbags for automobiles used to implement the formation of sodium azide as a source of nitrogen gas. This has since been replaced due to the potential caustic nature of the products. The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen oxide in liquid ammonia: 3N2O(g) + 4Na(s) + NH3(l)→ NaN3(s) + 3NaOH(s) + 2N2(g) a.

A 235.2-g sample of ground water is analyzed for calcium. The Ca2+ in the sample is first precipitated and filtered-off as NH4CaPO4·7H2O. This precipitate is dried and heated, releasing water and ammonia to yield anhydrous calcium pyrophosphate (Ca2P2O7). The mass of Ca2P2O7 obtained is 0.0234 g.Give the calcium content of the ground water in parts per million (to three significant figures).

Mass NaHCO3 = 6.9341 g 5. Calculate the moles of NaHCO3 in the sample and record the data below. 0.0825 mol 6. Drag the 25 mL empty graduated cylinder under the sink tap and hold it there till it fills with water. (When the graduated cylinder is full, it will automatically snap back into place.) Pour that water into the beaker with the NaHCO3. Then pour the beaker with the solution into the 50 mL graduated cylinder (the largest one). Hold the 50 mL cylinder under the tap until it fills with water to make an aqueous solution of NaHCO3. Note that the solid is added and dissolved before the volume is measured when making a molar solution. Chemists normally use a volumetric flask for making molar solutions, but this is not available in the simulation. Record the volume of the solution, in L, below. Volume NaHCO3 = 0.05 7. The molarity is calculated using the formula: L Calculate the molarity of the NaHCO3 solution in units of mol/L. M 8. If the density of the solution is 1.047 g/mL,…
