When collecting a gas by bubbling it out over water, what do you have to remember about the pressure of the gas you collect?     Nothing.  The water prevents atmospheric gases from mixing with your pure sample.     You must subtract the partial pressure of water vapor (which you look up in a chart)     You must do the stoichiometry of your gas reacted with water to form hydroxide ions in solution     You must know that it won't be anhydrous since it has reacted with water

A miner’s lamp burns acetylene (C2H2) that is produced from water dripping onto solid CaC2. The other product formed from the reaction is calcium hydroxide. What volume of water (d = 1.00 g/mL) is required to react with 12.5 g of calcium carbide (CaC2) in the lamp?

A student mixes solutions of barium chlorate and rubidium sulfate and observes the formation of a precipitate. Write the balanced chemical equation. Write the ionic equation. List the spectator ions(s). Write the net ionic equation.

In volumetric analysis, a substance of known concentration is used to determine the unknown concentration of some other substance. To carry out the volumetric analysis, the reaction between the two substances must occur in aqueous medium and must be a known reaction.   true or false

You have been asked to produce 40.0 g of barium carbonate. You have been given two solutions you can use in this reaction: a 0.160 mol/L solution of potassium carbonate, and a 0.260 mol/L solution of barium nitrate. It is known the reaction between these two compounds has a 72.0% yield of barium carbonate. What is the minimum volume of each solution should you use in this reaction?

Here is a graph of the molarity of thionyl chloride (SOC1₂) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. M 0.030- 0.025- 0.0219 0.020- 0.0176 0.015. 0.009703 0.005- 0 1011 seconds Is SOCI, being created or destroyed by the chemical reaction? If SOCI, is being created or destroyed, what is the rate at which it is being created or destroyed 11 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If SOCI, is being created or destroyed, what is the average rate at which it is being created or destroyed. during the first 11 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 24.513 created O destroyed 30 neither created nor destroyed 0 X 0 ☐ x10 믐 X ロ・ロ

158 g of aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide. Calculate the amount of aluminum hydroxide produced with excess water.

Hydrogen, when combined with oxygen in a chemical reaction, forms water. This is an example of which type of chemical reaction?

13. Nitric acid, HNO3, is a strong acid in aqueous solutions. It is sold commercially as a concentrated solution with a density of 2.14 kg.L-¹ and containing 58% mass of HNO3. We introduce 10.0 mL of this solution in a 250.00 mL volumetric flask which is then filled to the mark with distilled water. This solution is called S. S is then diluted 100 times to afford solution S'. a. What is the definition of a strong acid? | b. What is the concentration of solution S"? c. What is the pH of solution S'?
