I'm pretty sure that you multiply the number of moles by avogadro's number (6.02x10^23)... you may want to check.
The case is acidic since calculated pH is below 7 that is 2.3
The hydroxide and hydrogen ion levels in a solution are the sources for calculating pOH and pH levels, respectively, and are the basis of whether a solution is acidic or basic
[H₃O+]=5.3×10⁻³M
To determine the hydroxide ion concentration, we use:
[OH−][H3O+]=1×10⁻¹⁴
We isolate the hydroxide ion concentration:
[OH−]=1×10−145.3×10⁻³M
Solving this, we obtain:
[OH−]=1.9×10−¹²M
We can determine whether the solution is acidic or basic by calculating the pH level:
pH=−log[H3O+]
We substitute in the hydronium ion concentration given:
pH=−Log(5.3×10−3)pH=2.3
Since the pH is below 7, the solution is acidic

A specific combination of bonded atoms which always react in the same way, regardless of the particular carbon skeleton is known as the functional group. These are specific groups of atoms or bonds within organic molecules that accounts for the characteristic chemical reactions of those molecules. Examples of functional groups are the Carbonyl group, alkyl Halides, aldehydes and ketones among others.
Answer:
Adding one proton to an atom of lithium with 3 protons, 4 neutrons and 3 electrons would form a _beryllium ion_. The new atom have 4 protons and 4 neutrons since Be has a mass number of 9 then it has to form an ion. Hope this helps! PLEASE GIVE ME BRAINLIEST!!!! =)
Iron, but there are some amounts of other dense elements like gold, platinum, and uranium.
