There are two instances where waste streams from reactions would need to be processedcan you identify them?
Now, write the balanced equation for the reaction you just watched in question 4 (same video embedded below).
Hint: The reactants are solid copper and aqueous silver nitrate. There are two products in this reactions - one is a solid and one is an aqueous solution of an ionic compound. Copper becomes a +2 ion.
Please make sure to use phases for each substance and parentheses (when needed) and subscripts.

- On Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2HNO3(aq)+Na2CO3(aq)2NaNO3(aq)+H2O(l)+CO2(g) a. Calculate H for this reaction. Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? (Hf for NaNO3(aq) = 467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of H, what was their major concern?arrow_forwardWhen balancing a chemical equation, which of the following statements is false? l type='a'> Subscripts in the reactants must be conserved in the products. i>Coefficients are used to balance the atoms on both sides. i>The law of conservation of matter must he followed. i>Phases are often shown for each compound hut are not critical to balancing an equation.arrow_forwardMany over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward
- The element tin often occurs in nature as the oxide, SnO2 . To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous byproduct carbon monoxide. Write the unbalanced equation for this process.arrow_forwardWhen steel wool (iron) is heated in pure oxygen gas, the steel wool bursts into flame and a fine powder consisting of a mixture of iron oxides ( FeO and Fe2O3 ) forms.
