Determine the oxidation state of the metal ion in [co(nh3)5br]2+. express your answer as an integer.

Zanzabum

[Co(NH₃)₅Br]²⁺

Ligands and charges on them,

5 × NH₃ = 5 × 0 = 0

1 × Br⁻¹ = 1 × -1 = -1

Charge on sphere = +2

So, putting values in equation,

Co + (0)₅ - 1 = +2

Co + 0 - 1 = +2

Co - 1 = +2

Co = +2 + 1

Co = +3

Result:
Oxidation state of Co in [Co(NH₃)₅Br]²⁺ is +3.

What is the maximum amount in moles of P2O5P2O5 that can theoretically be made from 112 gg of O2O2 and excess phosphorus

Nastasia [14]

Answer:

$n_{P_2O_5}^{max}=1.4molP_2O_5$

Explanation:

Hello!

In this case, since the reaction between phosphorous and oxygen to form diphosphorous pentoxide is:

$2P+\frac{5}{2}O_2\rightarrow P_2O_5$

Thus, since phosphorous is in excess and oxygen and diphosphorous pentoxide are in a 5/2:1 mole ratio, we can compute the maximum moles of product as shown below:

$n_{P_2O_5}^{max}=112 gO_2*\frac{1molO_2}{32.00gO_2}*\frac{1molP_2O_5}{5/2molO_2}\\\\ n_{P_2O_5}^{max}=1.4molP_2O_5$

Best regards!
