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 leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
