Which reaction is a decomposition reaction? A. 2KClO3 → 2KCl + 3O2 B. 4Na + O2 → 2Na2O C. ZnS + 3O2 → 2ZnO + 2SO2 D. 2NaBr + CaF
Vedmedyk [2.9K]

Answer:

  • <em><u>Option A. </u></em><u><em>2KClO₃ → 2KCl + 3O₂</em></u>

Explanation:

There are five basic general types of chemical reactions:

  • Decomposition reactions
  • Synthesis or combination reaction
  • Single replacement reactions
  • Double replacement reactions
  • Combustion reactions

The given reactions are:

  • <u>2KClO₃ → 2KCl + 3O₂</u>

Which is, indeed, a decomposition reaction because the reactant, KClO₃, is a single substance that undergoes a reaction in which it yields two new substances, known as products: KCl and O₂.

  • <u>4Na + O₂ → 2Na₂O</u> is a synthesis or combination reaction because two reactants, Na and O₂, combine for the formation of one single new product, Na₂O.

  • <u>ZnS + 3 O₂ →  2ZnO + 2SO₂ </u>is a single replacement reaction because oxygen is replacing Zn and S in ZnS to form ZnO and plus SO₂.

  • <u>2NaBr + CaF₂ → 2NaF + CaBr₂ </u>is a double replacement reaction because two  ions (Br⁻ from NaBr and F⁻ from CaF₂) are exchanging places with other two ions (Na⁺ from NaBr and Ca²⁺ from CaF₂) two form two new ionic compounds (NaF and CaBr₂).

Which of the following pairs contains a conjugate acid-base pair?
zzz [600]
Remember that a conjugate acid-base pair will differ only by one proton. 
None of the options you listed are conjugate acid-base pairs as none of them differ only by one proton (or H⁺)
An example of a conjugate acid-base pair would be NH₃ and NH₄⁺NH₃ + H₂O --> NH₄⁺ + OH⁻NH3 is the base, and NH₄⁺ is the conjugate acid
