The percentage of elements in the compound is determined from the number of elements in the compound
<h3>Further explanation </h3>
Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements
Example
% Lithium (Li) in Li₂CO₃(lithium carbonate)
Ar of Li = 6.941 g/mol
MW of Li₂CO₃ = 73.891 g/mol
Answer:
H3PO4
Explanation:
Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H ₃PO ₄. The pure compound is a colorless solid. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H⁺ ions.
Answer:
Explanation:
a ) Benzoic acid is formed . In any alkyl benzene derivative , potassium permanganate reacts to form carboxylic acid . It oxidises side chains to carboxylic acid .
C₆H₅CH₃ + 0 = C₆H₅COOH + H₂O
O is provided by KMnO₄
b ) In this reaction isophthalic acid is formed .
C₆H₄(CH₃)₂ +O = C₆H₄(COOH)₂
c)
4-Propyl-3-t-butyltoluene
In this oxidation , three side chains of ring are 1 ) 1-methyl 2 ) 3- butyl 3 ) 4 propyl .
The methyl and 4 - propyl groups are oxidised to di- carboxylic acid and 3 butyl group remains intact ( unoxidised )
<em>Transparent because you can see right through it </em>
Answer:
CaCO3
Explanation:
The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3−2.
