An ideal gas (fixed amount) undergoes an isothermal expansion from 10.0 bar to 1.0 bar either (1) re versibly, (2) against a non-zero constant external pressure, or ге- (3) freely against a vacuum. the values of the magnitude of the work obtained from these processes are eill in the question marks with equalities or inequalities (equals, less than, greater than).

Its trait is different and it the organism survive

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻
