Suppose you used excess sulfuric acid in all the flasks. how many moles of co2would be released in flask 7? the molar mass of sodium carbonate is 105.99 g/mol.

Number of produced moles of carbondioxide is 0.113 mol.

Explanation:

Excess of sulphuric acid is present.And the sodium carbonate is completely consumed.

Molar mass of sodium carbonate = 105.99g/mol

Given mass of sodium carbonate =12 g/mol

one mole of sodium carbonate produce one mole of carbondioxide.

0.113 mole of sodium carbonate produce 0.113 mole of carbondioxide.

Therefore, 0.113 mol of carbondioxide produced in flask 7.

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.
