When MnO_(2) is fused with KOH in air, it gives

Compound that is both paramagnetic and coloured is

MnO_2 is the most important oxide of manganese. MnO_2 occurs naturally as the black coloured mineral pyrolusite. It is an oxidising agent, and decomposes to Mn_3O_4 on heating to 530^(0) C. It is used in the preparation of potassium permanaga-nate and in the production of Cl_2 gas. Over half a million tonnes per year of MnO_2 is used in dry batteries When MnO_2 is fused with KOH in the presence of air, the product formed is :
