Chapter 5: Problem 128

Write an equation to show how sulfuric acids in acid rain reacts with marble and limestone. (Both marble and limestone are primarily calcium carbonate.)

Short Answer

Expert verified
\(H_2SO_4 + CaCO_3 \rightarrow CaSO_4 + H_2O + CO_2\)

Step by step solution

01

Write the unbalanced equation

First, let's write out the unbalanced chemical equation using the chemical formulas for the reactants and products: H2SO4 + CaCO3 鈫� CaSO4 + H2O + CO2
02

Balance the equation

Now, we need to balance the equation by ensuring that there are equal numbers of each element on both sides of the equation. Let's examine the equation element by element: - H (Hydrogen): We have 2 hydrogen atoms in sulfuric acid (H2SO4), and 2 hydrogen atoms in water (H2O). - S (Sulfur): There is 1 sulfur atom in sulfuric acid (H2SO4), and 1 sulfur atom in calcium sulfate (CaSO4). - O (Oxygen): We have 4 oxygen atoms in sulfuric acid (H2SO4), 3 in calcium carbonate (CaCO3), 4 in calcium sulfate (CaSO4), 1 in water (H2O), and 2 in carbon dioxide (CO2). This totals to 7 oxygen atoms on the reactant side and 7 oxygen atoms on the product side. - Ca (Calcium): There is 1 calcium atom in calcium carbonate (CaCO3) and 1 calcium atom in calcium sulfate (CaSO4). - C (Carbon): We have 1 carbon atom in calcium carbonate (CaCO3) and 1 carbon atom in carbon dioxide (CO2). As it turns out, the original unbalanced equation is actually balanced: H2SO4 + CaCO3 鈫� CaSO4 + H2O + CO2
03

Write the balanced equation

Now that we have balanced the equation, let's write it out in its final form: \(H_2SO_4 + CaCO_3 \rightarrow CaSO_4 + H_2O + CO_2\) This balanced equation represents the reaction between sulfuric acid in acid rain and calcium carbonate in marble and limestone, producing calcium sulfate, water, and carbon dioxide.

A sealed balloon is filled with 1.00 \(\mathrm{L}\) helium at \(23^{\circ} \mathrm{C}\) and 1.00 atm . The balloon rises to a point in the atmosphere where the pressure is 220 . torr and the temperature is \(-31^{\circ} \mathrm{C}\) . What is the change in volume of the balloon as it ascends from 1.00 atm to a pressure of 220 . torr?

A 2.747 -g sample of manganese metal is reacted with excess \(\mathrm{HCl}\) gas to produce 3.22 \(\mathrm{L} \mathrm{H}_{2}(g)\) at 373 \(\mathrm{K}\) and 0.951 atm and a manganese chloride compound \(\left(\mathrm{Mn} \mathrm{Cl}_{x}\right)\). What is the formula of the manganese chloride compound produced in the reaction?

Hyperbaric oxygen therapy is used to treat patients with carbon monoxide poisoning as well as to treat divers with the bends. In hyperbaric oxygen therapy, a patient is placed inside a 7.0-ft cylinder with a 3.0-ft diameter, which is then filled with oxygen gas to a total pressure of 2.50 atm. Assuming the patient takes up 32.0% of the chamber鈥檚 volume, what volume of \(\mathrm{O}_{2}(g)\) from a gas cylinder at \(25^{\circ} \mathrm{C}\) and 95 \(\mathrm{atm}\) is required to fill the chamber to a total pressure of 2.50 \(\mathrm{atm}\) at \(25^{\circ} \mathrm{C} ?\) Assume the hyperbaric chamber initially contains air at 1.00 atm before \(\mathrm{O}_{2}(g)\) is added.

The partial pressure of \(\mathrm{CH}_{4}(g)\) is 0.175 atm and that of \(\mathrm{O}_{2}(g)\) is 0.250 \(\mathrm{atm}\) in a mixture of the two gases. a. What is the mole fraction of each gas in the mixture? b. If the mixture occupies a volume of 10.5 \(\mathrm{L}\) at \(65^{\circ} \mathrm{C}\) , calculate the total number of moles of gas in the mixture. c. Calculate the number of grams of each gas in the mixture.

A mixture of cyclopropane and oxygen is sometimes used as a general anesthetic. Consider a balloon with an anesthetic mixture of cyclopropane and oxygen at 170. torr and 570. torr, respectively. Calculate the mole fraction of cyclopropane in the mixture.
