Consider the following chemical reaction: AgNO3 (aq) K2CrO4 (aq) > Ag2CrO4(s) KNO3(aq) 2.24 g of silver nitrate is mixed with excess of potassium chromate. Calculate yield% of silver chromate if the actual yield is 1.90 g. AgNO3

ok whats the question if not i cannot you i need question and need a thing to answer

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.
