Sodium carbonate, na2co3(s), can be prepared by heating sodium bicarbonate, nahco3(s). 2nahco3(s) > na2co3(s) + co2(g) + h2o(g) kp = 0.23 at 100ºc if a sample of nahco3 is placed in an evacuated flask and allowed to achieve equilibrium at 100ºc, what will the total gas pressure be? 0.46 atm 0.96 atm 0.23 atm 0.48 atm 0.11 atm

The equilibrium will be

There is no gas in the reactant

The Kp expression for equilibrium will be

Kp = pH₂O X pCO₂

Given Kp =0.23

thus

0.23= pH₂O X pCO₂

The partial pressures of both will be equal, lets say "p"

0.23=p²

p=0.48

Total pressure = 0.48 + 0.48 = 0.96 atm

Answer is 0.96 atm

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
