How strong is silver?
well if you need some scientific way of answering, silver has - Young's modulus - 83 GPa Shear modulus - 30 GPa Bulk Modulus - 100 GPa Poisson ratio - 0.37 Mohs hardness - 2.5 Vickers hardness - 251 MPa Brinell Hardness - 24.5  MPa Silver is a very ductile and malleable (slightly harder than gold) Bulk modulus - Brinell hardness -
Why there is no free rotation around a double bond?
a double bond consists of a sigma bond and a pi bond .....pi bond is formed by sideways overlapping of unhybridized p-orbitals of two carbon atoms above and below the plane of carbon atoms..if now one of the carbon atoms of double bond is rotated with respect to the other ,the p-orbitals will no longer overlap and pi bond should break....but the breaking of pi bond requires 251 kj/mole of energy which is not provided by collision of molecules at room temperature...consequently the rotation about a carbon-carbon double bond is not free but is strongly hindered or restricted.... while in carbon-carbon single bond only 12.55 kj/mole of energy is reacquired (this data is for ethane molecule) .....at room temperature the collission of molecules supply sufficient kinetic energy to overcome this energy barrier
