Tin (Sn) is a pure metal.Predict the state of tin at room temperature.LiquidGasSolid

Theheat ofthe reaction Sn (grey) = Sn (white) J/kg) is 500 cal/mole (2,092 J/mol) at the transition temperature of 13°C (286 K). The atomic weight of tin is 118.7 and the densities of grey and white tin are 5.75 g/c.c. (5.75 x IO3 kg/m3) and 7.28 g/c.c.(7.28 xlO3 kg/m3 ) respectively.Calculate the change in the transition temperature if the pressure on the grey tin phase is increased by 100 atm (101,325 x 10 N/m ) .

Tin is a solid at room temperature.Which one of the following explains why tin is a solid at room temperature?It has a high boiling & melting point.It has a high density.It is malleable.It is ductile.

Sn2+ looses 2 electrons in a reaction. What will be the oxidation number of tin after the reaction?
