12. Baking powder is made up of sodium hydrogen carbonate and calcium hydrogen phosphate. When baking powder is wet, these components
react to produce carbon dioxide. The equation for
this reaction is given below:
NaHCO,(aq) + CaHPO, (aq) - NaCaPO (aq) + CO2(g) + H2O(1)
How many liters of carbon dioxide can be formed at room temperature from 4.00 g of NaHCO;
and excess CaHPO,?

Why are the trends and exceptions to the trends in ionization energy observed?

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
