Please help will give brainliest What is the mole fraction of NaOH in
an aqueous solution that contains
15.0% NaOH (weight/weight %)?
Molar Mass
NaOH: 39.998 g/mol
H20: 18.016 g/mol

You need to divided twenty four by a dozen them by the temperature it is getting cook by

Hello thereone of the following properties was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version. which property fits this description? answer: atomic mass  was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

Idon't mean to be a smart alec, length of atoms' bonds is the simplest way to define it.

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⁻
