Question:When solid sodium carbonate reacts with hydrochloric acid, sodium chloride, water and a gas are formed. What gas is formed? sulfur dioxide carbon monoxide carbon dioxide hydrogen gas

Answers:Carbondioxide Na2Co3 + 2HCl-----2NaCl + H2O + CO2

Question:I know how the reaction works and everything, but i need to prove that the gas created from this is CO2 in fact, by holding a splint. usually the splint goes pop for reactions that are reacted with HCL and a metal, because of the hydrogen gas. But what about the CO2 gas, what does that do to the splint?

Answers:CO2 is used in fire extinguisher. it puts out a burning splint.

Question:Sodium carbonate reacts with acetic acid to produce carbon dioxide gas, aqueous sodium acetate and water. if 75mL of .30M acetic acid is allowed to react with excess sodium carbonate, then how many mL of dry carbon dioxide gas are produced at 22*C and 745 mm Hg? Zinc metal reacts with aqueous hydrochloric acid to produce aqueous zinc chloride and hydrogen gas. if 20 grams of zinc is allowed to react with excess hydrochloric acid, then what is the volume in liters of dry hydrogen gas collected at 35*C and 733 mm Hg? What are the steps to solve these questions? Thank you for the help.

Answers:Question: Sodium carbonate reacts with acetic acid to produce carbon dioxide gas, aqueous sodium acetate and water. if 75mL of .30M acetic acid is allowed to react with excess sodium carbonate, then how many mL of dry carbon dioxide gas are produced at 22*C and 745 mm Hg? To work this one, first write down the chemical reaction. Then you want to balance it with stochemetry. Next, you want to figure out the limit reagent, so you can figure out how many moles of product are produced. Finally, you want to figure out how much volume the number of moles of CO2 would have. The second question is similar.

Question:

Answers:... and carbon dioxide.

Sodium Carbonate and Hydrochloric acid :The reaction between sodium carbonate and hydrochloric acid is investigated. Limewater is used to test the gas given off. (Music by free-loops.com Creative commons)

04 - Sodium reacts with water and hydrochloric acid :In this video, sodium reacts with water and hydrochloric acid IMPORTANT NOTE: Both reactions must be performed in a wide container to evenly distribute the heat of the reaction. Do NOT perform these reactions in a test tube, it will probably explode. REACTION WITH WATER: A few drops of cabbage indicator were dropped in the water to indicate the presence of sodium hydroxide. REACTION WITH HYDROCHLORIC ACID: The violent reaction of a small piece of sodium and dilute (~2M) HCl is demonstrated. No pH indicator was added.
