Amalgam (chemistry) organic synthesis (e.g., for the Clemmensen reduction). It is the reducing agent in the Jones reductor, used in analytical chemistry. Formerly the zinc plates of dry batteries were amalgamated with a little mercury to prevent deterioration in storage. It is a binary solution (liquid-solid) of mercury and zinc. For the alkali metals, amalgamation is exothermic, and distinct chemical forms can be identified, such as KHg and KHg. KHg is a gold-coloured compound with a melting point of 178 °C, and KHg a silver-coloured compound with a melting point of 278 °C. These amalgams are very sensitive to air and water,
What is Living and What is Dead in Indian Philosophy What is Living and What is Dead in Indian Philosophy What is Living and What is Dead in Indian Philosophy is a 1976 book by Debiprasad Chattopadhyaya. Explaining the relationship between the soul and consciousness in the Nyaya-Vaisesika philosophy, Debiprasad Chattopadhyaya makes three points.

Third, consciousness is a transient quality, not a permanent quality. By itself, the soul is without consciousness; consciousness is produced in the soul only when it is conjoined with certain other entities. Hiriyanna,
