<span>Metals are good conductors of electricity because of the free electrons that is present in their outer shell that makes them good conductors of electricity. This is the most accepted fact that for any thing to transmit electricity by being a good conductor they need more free electrons in their outer shell</span>

metal   have   free electrons  in  their   outer  shell  which  make  them  generally  good  conductors  of  electricity. Example  is  the  copper  which   is  used  for  electrical  wiring   since  is  a good  conductor  of  electricity.  copper  with   electronic configuration  of  (Ar)4s2 has  two  free  electrons  in  their  outer  most shell which  allow  it  to  conduct  electricity.

sweet [91]

Answer: Equilibrium concentration of [Cl^-] at 50^0C is 4.538 M

Explanation:

Initial concentration of CoCl_2 = 0.056 M

Initial concentration of Cl^- = 4.60 M

The given balanced equilibrium reaction is,

               COCl_2+2Cl^-\rightleftharpoons [CoCl_4]^{2-}+6H_2O

Initial conc.          0.056 M      4.60 M        0 M       0 M

At eqm. conc.     (0.056-x) M   (4.60-2x) M   (x) M    (6x) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[CoCl_4]^{2-}\times [H_2O]^6}{[CoCl_2]^2\times [Cl^-]^2}

Given : equilibrium concentration of [CoCl_4]^{2-} =x =  0.031 M

Concentration of Cl^- = (4.60-2x) M  = (4.60-2\times 0.031) =4.538 M  

Thus equilibrium concentration of [Cl^-] at 50^0C is 4.538 M

H2(g)+p4(s)ph3(g) what the answer ?
disa [49]

Answer:

6H2 + P4→ 4PH3

Explanation:

Phosphorus has 4 in it and hydrogen has 3 in it. in order to balance it, we have to put 4 in front of phosphine so that the phosphorus on the product side has an equal amount as to the one on the reactant side.

the only one left to balance is hydrogen and so in order to balance it we put a 6 on h2 because the hydrogen in the product size becomes 12 (4 * 3).

therefore the hydrogen on the reactant side becomes 12 as well (6 * 2)
