Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
The three types of chemical reactions are: synthesis, decomposition, and replacement.
Metabolism and/or catabolism.
Chemical Change
Matter that does not enter chemical reactions is described as inert. This type of matter cannot be altered by chemical reactions.
iron
Solid state
because yes!
These are not chemical reactions but thermonuclear reactions.
The Arrhenius equation describes a number of temperature dependent chemical reactions. These comprise not just the forward and reverse reactions, but also other reactions that are thermally influenced such as diffusion processes.
Chemical reactions are abbreviated by their chemical equations.
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
Rate constants in chemical reactions are temperature dependent because as temperature increases, the molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that rate constants increase exponentially with temperature.
Autotrophic plants. You've described photosynthesis, basically.
When a chemical reaction is described as being "thermodynamically favored," it means that it requires a great deal of activation energy for it to occur.
