Disinfection with vodka is not sufficient because the concentration of ethanol is only approx. 40 %. The toothbrush is not affected.
These are not chemical reactions but thermonuclear reactions.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
A catalyst helps chemical reactions occur.
These chemical reactions are named exothermic.
materials used in chemical reactions are reactants
These are not chemical reactions but thermonuclear reactions.
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.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
The chemical energy of the battery in your toothbrush is turned into radiant energy (heat), and kinetic energy (movement).
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
Chemical reactions are chemical processes.
IT ACCELATATES THE CHEMICAL REACTIONS
enzymes involve in bio chemical reactions.
chemical reactions are going on in our bodies all of the time
These chemical reactions are named exothermic.
A catalyst helps chemical reactions occur.
