Answer;
D. C6H6, C2H5OH, C6H5CH3, and C3H5(NO3)3.
Explanation;
-Organic compound are chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen, like the examples above in choice D. . Inorganic Compounds
on the other hand, are compounds made from any elements except those compounds of carbon, such as CaSO4, CaCl2 and Ca3(PO4)2 in A, B and C respectively.
The answer is choice C - there are approx. 509.93682609599995 grams in <span>Al2S3.</span>
Answer:
Stongest Acid to Weakest Acid (↓)
HX
HY
HZ
Explanation:
<u><em>"The strongest acid contains most ions and lesser undissociated molecules in a solution."</em></u>
Here, HX is the strongest acid because all the HX molecules have been dissociated into ions. Hence, no undissociated molecule is present in HX anymore.
While HY contains half ions and half molecules and HZ contains a lesser number of ions than HY in a solution making it the weakest acid.
