For the following reaction, how much energy would be needed to produce 3 moles of na2co3? show work. 2nahco3+85kj yields na2co3+h20+co2

The given reaction is rewritten below,

    2NaHCO3 + 85kJ --> Na2CO3 + H2O + CO2

It can be concluded that every 2 moles of NaHCO3 one needs 85kJ of energy. To determine the amount of energy needed for 3 moles of NaHCO3, the concept of ratio and proportion may be used.

       (85 kJ/ 2moles NaHCO3) (3 moles NaHCO3)
     = 127.5 kJ

127.5 kJ

A. ​it generates energy from carbohydrates.b. it requires activation by oxygen.​c. ​it is used by cells to dispose of excess electrons
