Answer:
Explanation:
the species that will be oxidized first will depend upon their oxidation potential .
oxidation potential are given as follows
F⁻ = - 2.87 V , Br⁻ = - 1.09 V , Cl⁻ = -1.36 V, Mg⁺² = -2.37 V, Cu⁺² = +.34 V
Higher the oxidation potential , higher the tendency to be oxidised .
so Cu⁺² is easiest to be oxidised . F⁻ is to be oxidised most difficult.
The order from easiest to most difficult as follows
Cu⁺² > Br⁻ > Cl⁻ > Mg⁺² > F⁻
The amount of sig figs is three.

Ammonium hydroxide is basic
Step 1 : write a valanced equation..
NaOH + HCl 》NaCl + H2O
Step 2 : find the number of mole of HCl..
1000 ml ..contains 4.3 mole
15ml... (4.3÷1000)×15 =...
Stem 3 : use mole ratio....
HCl : NaOH
1 : 1
So mole is same as calculated above...
Step 4 :
3.5 mole of NaOH is in 1000ml
(4.3÷1000)×15 mole is in ....
Do the calculation
