`SO_(2), CrO_(3), SO_(3), Al_(2)O_(3)` No of compounds that acts as oxidant as well as reluctant is

Among Al_(2)O_(3),SiO_(2),P_(2)O_(5) and SO_(3) the correct order of acid strength is :-

Assertion (A): O_(3) can act as an oxidising agent as wll as a reducing agent, but SO_(2) can act only as an oxidant. Reason (R ): The oxidation number of O in O_(3) is zero, and the oxidiation number of S in SO_(2) is +4 .

From - SO_(2), SiO_(2), Al_(2)O_(3), MgO, CO, Na_(2)O - Select an oxide which dissolves in water forming an acid

The depression of freezing points of 0.05 molal aqueous solution of the following compounds are measured. 1. NaCl 2. K_(2)SO_(4) 3. C_(6)H_(12)O_(6) 4. Al_(2)(SO_(4))_(3) Which one of the above compounds will exhibit the maximum depression of freezing point ?

Assertion : Out of CrO_(3)& Al_(2)O_(3), CrO_(3) having lower melting point than Al_(2)O_(3) . Reason: Oxidation state of Cr in CrO_(3) is high

Na_(2)SO_(3),Na_(2)S_(2)O_(3),Na_(2)CO_(3),Na_(2)CrO_(4) are separately treated with AgNO_(3) solution in how many cases is/are red ppt abtained ?

Dioxygen directly reacts with nearly all metals annd non-metals except some metals (e.g., Au, Pt) and some noble gases and form oxide(s). Oxides can be simple (e.g., MgO, Al_(2)O_(3) ) or mixed (Pb_(3)O_(4),Fe_(3)O_(4)) . Simple oxides can be classified on the basic of their acidic, basic or amphoteric character. an oxide that combines with water to give an acid is termed acidic oxide (i.e., SO_(2),Cl_(2)O_(7),CO_(2),N_(2)O_(5) ). for example, SO_(2) combines with water to give H_(2)SO_(3) , an acid. Q. If, Then select incorrect statement with respect to gas 'X'
