Atoms of different elements unite during chemical changes to produce at least one chemical compound.
Some chemical reactions produce heat, these are called exothermic
Magnesium is a chemical that burns with a white flame. In pyrotechnics, the different chemicals used will produce different color flames. So in order to produce a white sparkle effect, magnesium is added.
Gaseous molecules are always in continuous random motion so they collide with each other if they are of different elements or compounds and are properly oriented then their effective collisions may produce another substance or they may undergo the chemical reactions.
Lichen produce acids that can slowly break down rock in the process of chemical weathering. Acids in water and air also produce chemical weathering.
yes different parts of the country produce different amounts of rubbish
Chemical elements are combined to produce chemical compounds.
chemical changes
A chemical change always changes the chemical composition of the reactants to produce products with new and unique properties, different from the reactants.
Yes, it is correct.
This is the aptitude of chemical elements to do chemical reactions and to produce compounds.
If you were referring to two actual atoms they were not listed. When two atoms of different chemical elements bond together they form a chemical compound.
yes
a compoundCOMPOUND
Some chemical reactions produce heat, these are called exothermic
A chemical change. Chemical changes can also be indicated if energy is given off. Physical changes on the other hand do not produce energy or produce new substances.
Cooking food (including frying it) does produce chemical changes.
Both produce new molecules.
