Match the following. 1.The negative log of the hydrogen ion concentration of a solution; a scale ranging from 0 to 14 with 7 being neutral, values less than 7, acidic and greater than 7, basicpH
2.The product of a neutralization reaction, a substance consisting of a positive ion from the base and a negative ion from the acidneutralization
3.The reaction which occurs between acids and basessalt

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
