If 150 G of wood started Burning, and 30 G of wood ash was left behind, how many grams of CO2 to gas was released

120G

Explanation:

From the combustion process, about 120G of carbon dioxide would be released into the atmosphere.

For the chemical reaction to obey the law of conservation of matter, if only ash and carbon dioxide are the product, then the sum of the mass of the product and that of the reactants must be the same.

   In a chemical reaction, matter is not created nor destroyed, but they are simply changed from one form to another.

   Mass of wood burning  = mass of ash + mass of CO₂

              150G  = 30G + mass of CO₂

         mass of CO₂ = 150G  - 30G  = 120G

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i don,t know so just answer mine
