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.
= Reactants included
= Products formed
= Type of reaction(i.e. Oxidation, Reduction, Neutralization, Decomposition, etc )
- the nature of the reactants
- the nature of the products
- the amounts of compounds involved
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.
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.
A chemical equation is used in the means of writing out and describing a chemical reaction, such as the reactants and the substance that forms after the reaction (called the product)P.S: it took me a little to find out the question since i had it too. Some teachers decide to give out questions like these in attempt to get people to practice their research skills instead of just relying on a "magic book" for the answer.
The colour, the temperature and formation of gas
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
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.
1. formulas of reactants and products2. amounts of reactants and products3. sense of the reaction
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
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.

- 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

Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
No i believe that with three unknowns you must have three equal equations. Hope this helps! -dancinggirl25
