For a hydrogen fuel cell stack: the power is 10 kW, the voltage is 0.7 V, the operating temperature is 80 oC, the operating pressure is 220 kPa, the air stochiometry is 2, and the inlet air is at 70 oC and 70% relative humidity
. (1) what is the usage of hydrogen?
(2) What is the relative humidity of the exit air
please do 100% if you have any doubt let me know

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
