1. Which of the following is a single replacement reaction? CaO + H2O yields Ca(OH)2 Mg + 2HNO3 yields Mg(NO3)2 + H2 NaOH + HCl yields H2O + NaCl CH4 + 2O2 yields CO2 + 2H2O

The single  replacement  reaction  is

Mg + 2 HNO₃ →   Mg(NO₃)₂  +H₂

Explanation

  • Single replacement   reaction is type of chemical reaction in which element react with compound and take the place  of another element in that compound.
  • The reaction above  is a single replacement because  Mg ( an element) react   with HNO₃( a compound)  and Mg replaces H  from HNO₃  to Mg(NO₃)₂ and H₂
