Consider the balanced chemical equation below. when the chemical reaction was carried out calculated theoretical was yield for sodium bromide 162 grams but the measured yield was 150 grams what is the percent yield?

the answer is the first option

explanation:

just googled it m8. not that hard

lol

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.
