the main acid in the stomach is hydrochloric acid (hcl). which chemical equations show a reaction that occurs when someone takes an antacid? check all that apply.\n□ hcl + naoh → nacl + h₂o\n□ 2hcl + caco₃ → cacl₂ + co₂ + h₂o\n□ 2hcl + mg(oh)₂ → mgcl₂ + 2h₂o\n□ 6hcl + 2al → 2alcl₃ + 3h₂\n□ hcl + nahco₃ → nacl + h₂o + co₂\ndone
Answer
Answer:
B. $2HCl + CaCO_{3}\rightarrow CaCl_{2}+CO_{2}+H_{2}O$, C. $2HCl + Mg(OH){2}\rightarrow MgCl{2}+2H_{2}O$, E. $HCl + NaHCO_{3}\rightarrow NaCl + H_{2}O + CO_{2}$
Explanation:
Step1: Define antacid
Antacids are bases or basic salts.
Step2: Analyze each equation
- Equation A has NaOH which is not an antacid (too strong).
- Equation B: $CaCO_{3}$ is a common antacid, reacts with HCl.
- Equation C: $Mg(OH)_{2}$ is a common antacid, reacts with HCl.
- Equation D: Al reacts with HCl but is not an antacid - base - acid reaction.
- Equation E: $NaHCO_{3}$ is a common antacid, reacts with HCl.
