Asample of 1.59 grams of z is dissolved into 500 grams of water which is in a styrofoam coffee cup. the temperature is monitored and is found to drop from 23.669◦c to 23.384◦c. what is ∆hsolution for substance z? assume no heat is lost/gained by the cup itself. the specific heat of water is 4.184 j/g· ◦c and the molecular weight of z is 131 g/mol. answer in units of kj/mol of z.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
