Citric acid, c6h8o7, a component of jams, jells and fruity soft drinks, is prepared industrially via a fermentation of sucrose by the moid aspergillus niger. the equation representing this raction id :
c12h22o11 + h2o + 3o2 ? 2c6h8o7 +h2o
what mass of nitric acid is produced from exactly 1 metric on(1000 x 103 kg) of sucrose if the yield is 92.30%?

1.04 tonnes

Explanation:

As we have the equation balanced, we need to know, form the percent yield and the theoretical yield, the actual yield:

With this, we need to convert the mass of sucrose into moles:

Now, with the yield, we apply the rule of three, with the actual yield, to know the moles of citric acid produced:

Therefore, 5392.93 moles of citric acid are produced, now we need to know the mass:

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.
