If: the Initial mass of an unknown hydrate can be determined

then: the hydrate can be heated to dehydrate it and the mole ratio can be determined

because: the difference in this is equivalent to the water in the hydrate.

If we dry the hydrate then, what will remain is the amount of salt, all of the water will evaporate. We are then able to determine the masses of the salt and water and consequently be able to determine the number of moles by dividing the masses by the molar mass. Then, solve for the mole ratio.

Acetic acid (ch3cooh) can be a buffer, similar to carbonic acid. write the dissociation reaction, identifying the acid, base, h+
BARSIC [14]
The dissociation of acetic acid in water can be written as:

CH₃COOH + H₂O ↔ CH₃COO⁻ + H₃O⁺

The proton donor is CH₃COOH 
The proton acceptor is H₂O 
The acid is CH₃COOH 
The conjugate base is CH₃COO⁻

If the half-life of hydrogen-3 is 11.8 years, after two half-lives the radioactivity of a sample will be reduced to one-half of
maw [93]

Answer:

False

Explanation:

Half life is the time period at which the concentration of the radioactive substance in decay reduced to half.

<u>Thus, if the hydrogen-3 has gone 2 half lives, it means that it has first reduced to its half and then again the half of what it was, i.e. 1/4</u>

Thus, after two successive half-lives, the concentration must be 1/4 of the initial concentration and hence, the statement is false.

Mendeleev used his periodic table of elements to
pishuonlain [190]
<span>Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
</span>Mendeleev rewrote each edition of Principles of Chemistry<span>, including all new scientific data-particularly confirmations of the periodic law-and reanalyzing difficulties that had arisen to hinder its confirmation (inert gases, radioactivity, radioactive and </span>rare-earth elements<span>)
</span>he wanted to prove that he was right.
