To find the formula of the second oxide given the information about two oxides of a metal, we can follow these steps: ### Step 1: Determine the Atomic Mass of Metal (M) from the First Oxide We know the first oxide is \( M_2O_3 \) and contains 30.0% oxygen. 1. Calculate the total mass of oxygen in the first oxide: - The molar mass of oxygen (O) = 16 g/mol. - In \( M_2O_3 \), there are 3 oxygen atoms, so the total mass of oxygen = \( 3 \times 16 = 48 \) g. ...

The binary compounds of oxygen with other elements are called oxides. They are classified depending either upon their acid-base characteristics or on the basis of oxygen content. (a) Normal oxides : These oxides which contain oxygen atom as permitted by the normal oxidation number, i.e., -2 normal oxide may be acidic, basic, amphoteric or neutral. (b) Polyoxides : The oxides which contain oxygen atoms different than those permitted by the normal oxidation number of -2 . (i) Peroxides : Two oxygen atoms are linked to each other and oxyegen has -1 oxidation number. They contain (O -O)^(2-) unit. (ii) Superoxodes : These oxides contain (O-O)^(-1) unit, i.e., each O-atom has oxidation number -1//2 . (c) Suboxides : These contain low content of oxygen than expected. (d) Mixed oxides : These oxides are made of two simpler oxides. Which of the following oxides is paramagnetic in nature ?
