you can not.
no... chemical reactions happen in nature however you can stop the two objects from combining
Chemical reactions may be slowed by lowering the temperature, but unlikely to stop all together.Nuclear reactions may be stopped by interposing an appropriate screen, such as a dense material, or at least one that is dense to radiation.
i do not know one bit
The light reactions will slow down.
Everywhere. Different reactions are happening in different places. The sum of all these reactions keeps the cell alive.
These are not chemical reactions but thermonuclear reactions.
lol n00b
Chemical reactions are abbreviated by their chemical equations.
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Photosynthesis,see I answered it for you.Now stop relying on on this for your homework.
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.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
