The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
A chemical reaction
colour change fizzing new substance produced
substances can change to a solid, gas or liquid. solid - precipitate gas - fumes liquid - color change Either way, since its a chemical reaction, there always will be a change in the chemical composistion of a substance.
The absorption of water is not a chemical reaction.
A substance by itself will not slow down a chemical reaction; factors require change, such as cooling the reactants or lowering the concentration, to do so. Adding another chemical or substance that happens to slow a reaction often does so by actually interfering with the reaction and replacing or preventing it outright, and there is not a name for chemicals that do this -?inhibitor?-, since a chemical may do this to one reaction, but be a catalyst to another.Added:decrease surface area/ remove catalyst/ decrease temperature/ decrease concentration/ add inhibitor/ dilute reactants/ separate reactants/
A chemical reaction
The conversion of one substance to another substance is a chemical change, which happens as a result of a chemical reaction.
When a chemical reaction occurs Bonds are broken and new bonds are formed, resulting in a new substance.atoms of a molecule in the original substance are rearranged to make a new substance
substance
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
chemical bonds.
A chemical change occurs when this happens.
the rate of the reaction can be increased or decreased
Nothing, it just bonds with another atom, radical.
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
A Combustion reaction. It usually happens between a gas and oxygen. The products are CO2 and H2O.
