An element X forms two oxides XO and `XO_(2)`. The oxide XO has no action litmus solution but oxide `XO_(2)` turns litmus solution red.
(a). What is the nature of oxide XO?
(b). What is the nature of oxide `XO_(2)`?
(c). Would you call element X a metal or a non-metal? Give reason for you choice.
(d). Can you give an example of element like X?

An element X forms two oxides XO and XO_(2) . The oxide XO is neutral but XO_(2) is acidic in nature. The element X iis most likely to be:

The elements whose oxides can turn litmus solution red are:

An element E forms an oxide E_(2)O . An aqueous solution of E_(2)O turns red litmus paper blue. (a). What is the nature of the oxide E_(2)O ? (b). State whether element E is a metal or a non-metal. (c). Give one example of an element like E.

An element X forms an oxide which turns red litmus blue. The element is a

Metal A burns in air, on heating, to form an oxide A_(2)O_(3) whereas another metal B burns in air only on strong beating to form an oxide BO. The two oxides A_(2)O_(3) and BO can react with hydrochloric acid as well as sodium hydroxide solution to form the corresponding salts and water. (a). What is the nature of oxide A_(2)O_(3) ? (b). What is the nature of oxide BO ? (c). Name one metal like A. (d). Name one metal like B.
