What is the emprical formula of vanadium oxide , if `2.74g` of the metal oxide contains `1.53g` of metal ?

metal combines with oxygen to form two oxides, having the following composition: (i) 0.398 g of the first metal oxide contains 0.318g of metal. (ii) 0.716 g of the second oxide contains 0.636g of the metal. Show that the above data agrees with the law of multiple proportions.

Nitrate is converted into metal oxide on heating. This metal is:

What is the nature of alkali metal oxides and hydroxides?

Oxides of which metal upon heating producess metal

4 g of a metal oxide contains 1.6 g-oxygen, then equivalent mass of the metal is

1.40 g of a metal when heated in a current of oxygen gave 1.93 g of the metal oxide. Calculate the equivalent weight of the metal.

What are oxide ? Give two examples for each of metallic and non - metallic oxides .

1.60 g of a metal were dissolved in HNO_3 to prepare its nitrate. The nitrate was strongly heated when 2.0 g of the metal oxide was obtained. Calculate the equivalent weight of the metal.

Calculate the equivalent weight of metal, if the oxide of a metal contains 32% oxygen.

The oxidation state of metal in metal carbonyl is
