Concept explainers
(a)
Interpretation:
To write the formula of a compound of elements N that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.
(b)
Interpretation:
To write the formula of a compound of elements S that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.
(c)
Interpretation:
To write the formula of a compound of elements Cl that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.

- true or false(a) if a substance is oxidised, it is gaining electrons.(b) if an ion is oxidised, its oxidation number increases.arrow_forwardWrite chemical equations to represent the followingreactions.(a) Calcium phosphate is heated with silicon dioxide and carbon, producing calcium silicatephosphorus and carbon monoxide. The phosphorus and chlorine react to form phosphorustrichloride, and the phosphorus trichloride andwater react to form phosphorous acid.(b) Copper metal reacts with gaseous oxygen, carbon dioxide, and water to form green basic coppercarbonate, (a reaction responsible forthe formation of the green patina, or coating, oftenseen on outdoor bronze statues).(c) White phosphorus and oxygen gas react to formtetraphosphorus decoxide. The tetraphosphorusdecoxide reacts with water to form an aqueous solution of phosphoric acid.(d) Calcium dihydrogen phosphate reacts withsodium hydrogen carbonate (bicarbonate), producingcalcium phosphate, sodium hydrogen phosphate,carbon dioxide, and water (the principal reactionoccurring when ordinary baking powder is added tocakes, bread, and biscuits).arrow_forwardWrite balanced chemical equations for the acid-base reactions described here:(a) the weak acid hydrogen hypochlorite reacts with water(b) a solution of barium hydroxide is neutralized with a solution of nitric acidarrow_forward
