1.Brass gets discolored in air due to the presence of Oxygen. Brass constitute zinc and copper and these two elements are transition elements. Among the given options hydrogen sulphide is more electronegative. So when it react with brass, brass get discolored.

2.The metal which exist as a liquid at room temperature is mercury. Non-metal which exist as a liquid at room temperature is bromine.

3.One such chelate is chlorophyll, the green pigment of plants. In chlorophyll the central ion is magnesium, and the large organic molecule is a porphyrin. The porphyrin contains four nitrogen atoms that form bonds to magnesium in a square planar arrangement.

4.Most pencil cores are made of graphite powder mixed with a clay binder. Graphite pencils (traditionally known as "lead pencils") produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging.

5.Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum. Silver-mercury amalgams are important in dentistry, and gold-mercury amalgam is used in the extraction of gold from ore.
