Make the formulas of the indicated substances and the corresponding ones: oxides (a and b) and hydroxides (c and d)
Make the formulas of the indicated substances and the corresponding ones: oxides (a and b) and hydroxides (c and d) a) sulfuric acid b) iron (III) hydroxide c) copper (II) chloride d) sodium nitrate.
To complete this task, you must have knowledge of the topic “Valence”
Valence is the ability of atoms of chemical elements to form a certain number of chemical (covalent) bonds.
A) Sulfuric acid – H2SO4, the valence of sulfur in acid is VI, it corresponds to sulfur oxide with a valence of VI – SO3
B) Iron hydroxide III – Fe (OH) 3 the valence of iron in the compound is III, this compound corresponds to iron oxide III – Fe2O3
C) Copper chloride II – СuCl2, the valence of copper in this compound is II, this compound corresponds to a hydroxide with a copper valence equal to II – Сu (OH) 2
D) Sodium nitrate NaNO3 sodium valence in this compound is I, this compound corresponds to hydroxide with sodium valence I – NaOH
