There are three things that can slow down a chemical reaction. You can have an inhibitor, something that is used to decrease the rate of a reaction, you can decrease the temp. making it colder, and decreasing the surface area (it takes longer for something to dissolve like a whole sugar cube, when it takes only a matter or seconds for a spoon full of sugar to dissolve). Hope that helped!
If you need any more help, just comment.
Less heat
Less surface area
Less quantity of the element
Dilution of reactants in a non-reacting solvent
A decrease in temperature, surface area, pressure and concentration. If any of these 4 things are decreased, the rate of a chemical reaction will slow down.
Hope I helped =) x.
Adding an inhibitor will slow down a chemical reaction.
Decreasing surface area of a solid reactant
impurities
The mass of the reactants is equal to the mass of the products.The atomic nucleus reamain unchanged in chemicals involved.
There are five things:Color changeodorstate change (from liquid to solid, liquid to gas, etc...),gives off at precipitatea temperature change
- change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
Types of chemical reactions:- synthesis- decomposition- single displacement- double displacement
Some signs that a chemical reaction is taking place is color and temperature changes, and the formation of precipitates.
Yes because it has two out of three things which are heat and two things that make a gas which is also called a chemical reaction
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.

There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.

Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
