Single+Replacement+II

Station One single-replacement reaction, is when an element or ion moves out of one compound and into another Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) All simple metal with acid reactions are single displacement reactions. 2AgNO3(aq) + Zn(s) → 2Ag(s) + Zn(NO3)2(aq) A and B may not have the same charge when ions are formed therefore some balancing of the equation may be necessary As internet recourses I used “Wikipedia” and “Google”. A + BX → AX + B

Station 2 In galvanised steel, when the steel starts to corrode after the coating has been scratched, the zinc in the coating will undergo a single replacement reaction with the steel, forming zinc ions and iron atoms. Rust would be converted back to iron, in other words.

Another example occurred in the Statue of Liberty. The outer layers of the statue are made of copper, but the inner support was made of steel. When the copper started to react with air, forming a verdigris coating, a single replacement reaction caused the iron to convert the copper back to copper metal; the iron started to rust, and the entire inner support had to be replaced in the 1980s.

STATION 4 media type="custom" key="3678087" Station 5 Word Equation Magnesium + Hydrochloric acid yields magnesium chloride + Hydrogen Correct Formula and balanced correctly Mg+2HCl à MgCl2 +H2 The Reaction Type Single Replacement, Replacement of hydrogen in an acid by a more active metal.
