### Question:If HCl is added to each of the following substances, which will produce CO₂ gas?- ☐ KBr- ☐ CaCO₃- ☐ NaOH- ☐ HC₂H₃O₂### Explanation:This question asks which of the listed substances will react with hydrochloric acid (HCl) to produce carbon dioxide (CO₂) gas. When examining chemical reactions:- **KBr (Potassium bromide):** No reaction producing CO₂.- **CaCO₃ (Calcium carbonate):** Reacts with HCl to produce CO₂. This option will produce the gas through the reaction: \[ \text{CaCO}_3 (s) + 2 \text{HCl} (aq) \rightarrow \text{CaCl}_2 (aq) + \text{CO}_2 (g) + \text{H}_2\text{O} (l) \]- **NaOH (Sodium hydroxide):** Reacts with HCl, but does not produce CO₂. Instead, it forms water and salt.- **HC₂H₃O₂ (Acetic acid):** No reaction involving the production of CO₂ when mixed with HCl. The correct choice is **CaCO₃**.

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq)+NaHCO3(aq)→NaCl(aq)+H2O(l)+CO2(g) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 200.mL of a 0.089M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.

Assume you have 25 grams of glucose and 40 grams of oxygen as reactants for the following photosynthesis reaction: A) Glucose is the limiting reactant; You would need .1388 moles of glucose to use up all of the Oxygen (non-limiting reactant). B Glucose is the limiting reactant; You would need .208 moles of glucose to use up all of the Oxygen (non-limiting reactant). C Oxygen is the limiting reactant; You would need 1.25 moles of Oxygen to use up all of the glucose (non-limiting reactant). D Oxygen is the limiting reactant; You would need .8328 moles of Oxygen to use up all of the glucose (non-limiting reactant).
