Many toxic gases along with water vapour are emitted in vocanic eruptions. All such toxic gases include hydrochloric acid, sulfur dioxide, carbon dioxide, hydrogen sulfide and carbon monoxide. Methane is not produced in the volcanic eruptions.

Mercury and Bromine both will be in liquid state at room temperature. But mercury is metal. Hence, bromine is the only non metal which is in liquid state at room temperature.

Rust forms when oxygen reacts with chemicals in rocks, and that is often the case with many other elements in general. Like a copper nail being exposed to the air will rust.

Convection is the mode of heat transfer which involves bulk motion of a fluid to transfer heat. Energy transfer by convection is primarily restricted to fluids. Fluids can be both liquids and gases.

The compound with the molecular formula P4O10 is called Phosphorus pentoxide or tetraphosphorous decoxide. It is an anhydride of the Phosphoric acid.

Any two amino acids vary structure by the r-group, otherwise all amino acids are in the same structure. All amino acids have in common carboxyl group -COO , amino group -NH3+ and a hydrogen -H and a r-group which are all bonded to a central carbon.
