this passage describes a chemical reaction. read the passage. then, follow the instructions below. when tap water contains high levels of calcium, a substance called calcium carbonate (caco₃) can build up at the mouths of water faucets. this buildup, called limescale, can prevent water from flowing through a faucet properly. to remove the calcium carbonate, you can scrub the faucet with citric acid (c₆h₈o₇). citric acid combines with calcium carbonate to form calcium citrate (ca₃c₁₂h₁₀o₁₄), carbon dioxide gas (co₂), and water (h₂o). the calcium citrate washes away easily, allowing water to flow through the faucet again. complete the table to classify the substances in this chemical reaction. substance reactant product calcium carbonate (caco₃) calcium citrate (ca₃c₁₂h₁₀o₁₄) carbon dioxide (co₂) citric acid (c₆h₈o₇) water (h₂o)

Answer

Answer:

Substance Reactant Product
calcium carbonate ((CaCO_{3})) ✔️
calcium citrate ((Ca_{3}C_{12}H_{10}O_{14})) ✔️
carbon dioxide ((CO_{2})) ✔️
citric acid ((C_{6}H_{8}O_{7})) ✔️
water ((H_{2}O)) ✔️

Brief Explanations:

  • Reactants are substances that start a chemical reaction. In the passage, it is stated that "Citric acid combines with calcium carbonate", so (CaCO_{3}) and (C_{6}H_{8}O_{7}) are reactants.
  • Products are substances formed by a chemical reaction. The passage mentions that the reaction forms "calcium citrate, carbon dioxide gas, and water", so (Ca_{3}C_{12}H_{10}O_{14}), (CO_{2}), and (H_{2}O) are products.
