An element forms two oxides of `2.900 g` and `2.250 g` of these oxides each of found to contain `1.12 L` of `O_(2)` at `STP`. Which law of chemical combination is illustrated by these data?

Hydrogen and oxygen combines to form H_2O_2 . Which law of chemical combination is illustrated here?

Hydogen and oxygen combines to form H_2O and H_2O_2 . Which law of chemical combination is illustrated here?

Which law explains the chemical combination of elements in H_2O ?

Nitrogen forms various oxides. Identify the law of chemical combination illustrated here. Also state the law.

28 g of magnesium oxide is produced by the combination of 12 g of magnesium and 16 g of oxygen. Which law is illustrated by this data ?

Nitrogen forms various oxides as: Nitric oxide, nitrogen dioxide Identify the law of chemical combination illustrated by these data? (Hint: Formula of first oxide is NO)

1.0 g of an oxide of A contained 0.5 g of A. 4.0 g of another oxide of A contained 1.6 g of A . The data indicate the law of-

This law was proposed by Dalton in 1803 . According to this law , if two elements combune to form more than one compounds ,the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole number. For exemple, hydrogen combines with oxygen to form two compounds ,namely, water and hydrogen peroxide. Here, the masses of oxygen (i.e, 16g and 32g) which combine with a fixed mass of hydrogen (2g) bear a simple raio, i.e, 16 :32 or 1 :2 . An element forms two oxides .In one oxide ,one gram of the oxide containd 0.5g of the element. In another oxide, 4g of the oxide contains 0.8g of the element . Show that these data confirm the law of multiple proportion.
