Answer:
emissions by factories is the answer
Explanation:
Factories produce air pollution which is polluted air, the other options
decay of organisms, photosynthesis (convert light energy into chemical energy - and returns CO2), and cellular respiration are all of the ways carbon dioxide returns to the atmosphere.
Hope this helped! Have a nice day, be safe and healthy :)
Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.
Dissolving a solute in a solvent is an endothermic process hence providing heat favors the process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.
-2 cuz 20 negative minus 18 positive is -2

Water is a polar molecule. Because of this, it has both adhesion and cohesion. This means it sticks to other matter. Adhesion is when water sticks to different matter and cohesion means it sticks to identical molecules of itself. Water has hydrogen bonds that are attracted to the oxygen atoms in other molecules of H2O.
