0.100 mol of both H₂CO3 and KHCO3 are dissolved in 1.00 L of water. What reaction takes place when a small amount of HCI is added to this solution? O H₂O (aq) + K* (aq) → HK (aq) + H₂O (1) O H₂O (aq) + HCO₂ (aq) → H₂CO3(aq) + H₂O (1) O H₂0 (aq) + H₂CO3(aq) → H₂CO3* (aq) + H₂O (aq) O HCI (aq) + H₂CO₂ (aq) → H₂CO3(aq) + Cl (aq)

If you begin with 28.4 mL of 0.287 M HCl(aq) solution and mix it with 17.3 mL of 0.181 M NaOH(aq), what is the final pH when they are mixed together?HCl(aq)+ NaOH(aq)→ H2O(l) + NaCl(aq)

Write a balanced net-ionic equation for the neutralization reaction between CH3COOH (aq) and Ba(OH)2 (aq). 2 CH3COOH (aq) + Ba(OH)2 (aq) --> 2 CH3COO- (aq) + 2 H₂O (1) + Ba²+ (aq) 2 CH3COOH (aq) + 2 OH" (aq) --> 2 CH3COO(aq) + 2 H₂O (1) CH3COOH (aq) + OH" (aq) --> CH3COO (aq) + H₂0 (1) OH(aq) + OH- (aq) --> H₂O (1) 2 H (aq) + 2 OH- (aq) --> 2 H₂O (1)

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  150.mL  of a  0.053  M  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.
