What happen when sodium carbonate is heated?
When sodium carbonate is heated, it undergoes thermal decomposition to form sodium oxide, carbon dioxide, and water vapor. This reaction can be represented by the equation: Na2CO3 (s) -> Na2O (s) + CO2 (g) + H2O (g).
What will happen when the pH of water when the co2 is removed from the water?
When CO2 is removed from water, the pH of the water will increase. This is because CO2 dissolves in water to form carbonic acid, which decreases the pH of the water. Removing the CO2 will shift the equilibrium towards fewer hydrogen ions, resulting in a higher pH.
How does CO2 dissolve in water and what factors influence this process?
Carbon dioxide (CO2) dissolves in water through a process called diffusion, where the gas molecules move from an area of high concentration to low concentration. Factors that influence this process include temperature, pressure, and the presence of other substances in the water. Higher temperatures and lower pressures generally increase the rate of CO2 dissolution, while the presence of other substances can affect the solubility of CO2 in water.
How do you calculate dissolved CO2 with pH?
To calculate the dissolved CO2 concentration in water based on pH, you can use the following equation: log(CO2) = pH - 0.496. This equation assumes that the water has reached equilibrium with the atmosphere. Keep in mind this is a simplified estimation and actual concentration may vary based on other factors.
Why does carbon dioxide (CO2) decrease pH in water?
Carbon dioxide (CO2) dissolves in water to form carbonic acid, which lowers the pH of the water by increasing the concentration of hydrogen ions. This increase in hydrogen ions makes the water more acidic.
Does pH control the relative concentration of CO2 in water?
No. Rather, the CO2 concentration controls the pH. Other factors control concentration, such as temperature, pressure, contamination, and availability of CO2.
What will happen to the amount of CO2 if the pH decreases?
The concentration of carbon dioxide decrease.
What happens to water vapor concentration when carbon dioxide increases?
Co2 is a acidic gas. water turn acidic when CO2 dissolved.
What will happen when limestone is heated at a high temperature?
It will decompose according to: CaCO3(s) --> CaO(s) + CO2
Does gas turn to water when heated?
If a hydro-carbon is burnt it will make heat, CO2 and water however if a hydro-carbon is heated it will just expand into its surroundings

What happen when water gas heated under pressure in the presence of Zn O - Cr O?
Water gas is a mixture of CO and H2 and H2O. Over oxide catalysts the "water gas shift" reaction occurs that removes the CO by reacting it with water to produce CO2 and more H2. CO + H2O -> CO2 + H2
What happens to pH when co2 is removed from water?
When CO2 is removed from water, the pH of the water will increase. This is because CO2 reacts with water to form carbonic acid, which lowers the pH. Removing CO2 will shift the equilibrium towards the formation of H2O and CO2, leading to a decrease in the concentration of H+ ions and an increase in pH.
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.

How would the movement of CO2 be affected if the concentration of CO2 in the lungs was equal or higher than the concentration in the blood?
If the concentration of CO2 in the lungs was higher or equal the concentration in the blood, there will be no diffusion of CO2 in the air of the lungs. The person will suffocate in this situation.
