give a possible reaction mechanism for the conversion of a haloalkane to alcohol

reaction conditions are reflux (ie with heat) with conc. sodium hydroxide. the mechanism is just a standard Sn1 or Sn2 (uni- or di- molecular nucleophilic substition) depending on the haloalkane used. bulkie...

A 1kg mass is launched from the ground into the air at an angle of 30 degrees to the horizontal and with initial speed 25 ms^-1. Assuming negligible air resistance, how far from the starting point will the mass travel before it hits the ground?

1: Draw a diagram 2: Split the velocity into its horizontal and vertical components using trig. Vertical velocity: 25sin(30) Horizontal velocity: 25cos(30) 3: Work out forces on the mass to find vertical and...
