How to write the chemical equation of carbon incomplete combustion to produce carbon monoxide? The key does not understand the conditions. Do you really write "incomplete combustion "? How to write the chemical equation of carbon incomplete combustion to produce carbon monoxide? Key don't understand the conditions. Really write "incomplete combustion "? How to write the chemical equation of carbon incomplete combustion to produce carbon monoxide? The key doesn't understand the conditions. Do you really write "incomplete burning "?
No, write 2C+O2=2CO directly, the condition is heating or ignition, it can be seen from the equation that it is incomplete combustion, no need to note
Why doesn't precipitation occur when BaCl2 solution is introduced into SO2?
SO2 reacts with water to form sulfite. Sulfuric acid is weak acid, while hydrochloric acid is strong acid. Generally, weak acid can not react with strong acid salt solution.
The law of acid - salt double decomposition reaction is: strong acid to weak acid.
