The compound copper(ii) nitrate is a strong electrolyte. write the reaction when solid copper(ii) nitrate is put into water:

Electrolytes dissociate when dissolved in water to produce charged particles known as ions. Copper (II) nitrate contains copper (II) ions and nitrate ions.

As a strong electrolyte would dissociate completely to release the two kinds of ions. Thus indicate a complete reaction in the equation with the single-headed arrow .

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
