Write the formula of the coordination compound pentaamminecarbonatocobalt(III) iodide. Enclose the coordination complex in squar
7nadin3 [17]

Answer:

[Co(NH3)5CO3]I3

Explanation:

The naming of coordination compounds follows certain rules specified by IUPAC. Usually, the name of the complex makes it quite easy to deduce its structure.

"Pentaamine" means that there are five NH3 ligands as shown in the structure. The ligand carbonato is CO3^2-.  It has no prefix attached to it in the IUPAC name of the complex hence there is only one carbonato ligand present(recall that the complex has a coordination number of six). I did not enclose it within parenthesis as required in the question.

Lastly the III that appeared after the metal name "cobalt" shows its oxidation state. The iodide counter ions must then be 3 in number in order to satisfy this primary valency of the metal hence the inclusion of I3 in the structure of the complex.

Calculate the average obtained from the following weighings of the same object. Do not forget to include formulas, units, and th
bazaltina [42]

Answer:

10.4376 g

Explanation:

First we <u>calculate the sum of the weighings</u>:

  • 10.4375 g + 10.4381 g + 10.4373 g + 10.4376 g = 41.7505 g

Then we <u>divide the sum by the number of weighings to calculate the average:</u>

  • Number of weighings = 4
  • Average = Sum of weighings / Number of weighings
  • 41.7505 g / 4 = 10.4376 g
