Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2 A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ...

[H3O+] = 3.6 x 10-2 M

spayn [35]

Answer:

Explanation:

Hello there!

In this case, since this concentration of hydronium ions is given, we infer we may calculate that of the hydroxide ions, pH and pOH because no question was specifically given. That is why we proceed as follows:

- pH: Here, we use this concentration to calculate the pH according to the negative logarithm:

$pH=-log(3.6x10^{-2})=1.44$

Which means that the solution is acidic as the pH is less than 7.

- pOH: since the pH added to the pOH is 14, we can calculate the latter as follows:

$pOH=14-1.44=12.56$

- Hydroxide concentration: Given the pOH, we apply the antilogarithm to calculate such concentration as shown below:

$[OH^-]=10^{-pOH}=10^{12.56}=2.75x10^{-13}M$

Keep in mind, this is an arbitrary solution because no question was provided.

Regards!
