An unspecified amount of sulfuric acid is added to 1.19 g of solid barium chloride, then water is added to form a solution with a total volume of 1.72 L.  Assuming the reaction goes to completion and that the volume does not change during the reaction, what is the molarity of the solution with respect to barium sulfate?  You may assume that barium chloride is the limiting reactant.  (3 sf) The pertinent balanced chemical equation is: BaCl2 (aq) + H2SO4 (aq) à BaSO4­ (s) + 2 HCl (aq)

When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO₂ (s) + 2HCl(aq) →→→ CaCl₂ (aq) + H₂O(l) + CO₂(g) How many grams of calcium chloride will be produced when 30.0 g of calcium carbonate is combined with 13.0 g of hydrochloric acid? mass of CaCl₂: Which reactant is in excess? CaCO, HCI How many grams of the excess reactant will remain after the reaction is complete? mass of excess reactant: g g

The human body burns glucose (C6H₁2O6) for energy according to this chemical reaction: C6H12O6 +60₂-6CO₂ + 6H₂O The products of the reaction are carbon dioxide (CO₂) and water (H₂O). Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500. mL of air, which is typically enriched to 4% CO₂ and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 1.00 kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO₂ is 2.0 kg/m³. 0 ☐ ☐x10 X

The Apollo 13 mission astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide can remove carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. The astronauts have a 5 kg container of sodium hydroxide on the ship. The reaction to neutralize the air, remove carbon dioxide with sodium hydroxide is shown below CO2(g) + 2NaOH(s) ⟶⟶ Na2CO3(aq) + H2O(l)   The astronauts have 2 days left before they land on earth. You know that there are three astronauts, and each astronaut emits roughly 500. g of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? Calculate how much sodium hydroxide is required to remove all the carbon dioxide from the three astronauts.  Be sure to show all your work!

Because of the toxicity of mercury compounds, mercury(I) chloride is used in antibacterial salves. The mercury(I) ion Hg22+ consists of two bound Hg+ ions.How many grams of mercury(I) chloride are needed to saturate 4900 km3 of water (the volume of Lake Michigan)? (Ksp = 1.5 × 10−18) .

Suppose a 250. mL flask is filled with 1.3 mol of CO, 1.0 mol of CO, and 1.8 mol of H,. This reaction becomes possible: 2 CO (g) +H,0(g) – CO,(g)+H,(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of CO. You can leave out the M symbol for molarity. CO H20 co2 H2 initial ? change equilibrium

9. What is the mass of calcium chloride that will be produced when 23.25 mL of 0.2351 M hydrochloric acid reacts with 23.89 grams of calcium hydroxide? The products of the reaction are calcium chloride and water. How much of each reactant is left after the reaction is over? Units should be mL of the hydrochloric acid and grams for the calcium hydroxide.
