I have no idea what the word "good" means in the context of chemical reactions. Chemical reactions have no morality in and of themselves, they simply happen or don't happen. Or are you asking about the motives of the human chemists?
Sorry, as worded this question can not be answered.
Ammonia is good because it is a versatile chemical with various industrial uses, such as in cleaning products, fertilizers, and as a refrigerant. It is also used in the production of plastics and textiles. Additionally, ammonia is an effective household cleaner and disinfectant.
When solid smelling salts and aqueous sodium hydroxide are combined, a chemical reaction occurs leading to the formation of ammonia gas. This reaction is characterized by the release of heat and the production of white fumes. Ammonia gas is known for its sharp, pungent smell.
Yes, isopropylamine can be formed through the reaction of propanol and ammonia, typically in the presence of a catalyst or under specific conditions. The reaction involves the dehydroxylation of propanol followed by the addition of ammonia, leading to the formation of isopropylamine. However, this process may require elevated temperatures and careful control of reaction conditions to achieve a good yield.
The plastic bottle does not have to react with ammonia.
Mixing ammonia and alcohol can produce a chemical reaction that forms potentially harmful compounds such as ammonium acetate. This mixture can release harmful vapors and should be avoided due to the risk of irritation to the respiratory system and skin. Additionally, the reaction can be exothermic, leading to the generation of heat.
A leaving group is considered good in a chemical reaction if it can easily detach from the molecule, allowing the reaction to proceed efficiently. This is typically achieved when the leaving group is stable and can form a stable product after leaving the molecule.
If you see fizzing, bubbling, or a change in color. They're good signs of chemical reactions you can see. Also, smoke. If you see smoke, you probably have a chemical reaction.
A good example might be a steam locomotive. It starts with a chemical reaction, where carbon combines with oxygen in the firebox. This heats water to generate steam which drives the cylinders, which turn the wheels and make the locomotive move...a physical reaction. Or a gun, where a chemical reaction, the decomposition of a propellant creates gas which propels a bullet.
baking soda and vinegar and salt and ice
A chemical change. Color change is a good indicator of a chemical change.
Any chemical that may stop natural fermentation is not good for a septic tank. If your tank starts to smell mix yeast and sugar and flush it down the toilet. This will get it working as it should. It's like making beer or wine.
Yes, there is demand for chemical engg. if he is good at thermodynamics. reaction engineering and kinetics and process calculation... a chemical engg without these subject is nothing but a coolie...
