Why are combustion reactions considered exceptions to the rules of chemical reactions?
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
What is the difference between a reactant and a product in a chemical reaction?
Reactants are the starting materials in a chemical reaction that undergo a change, while products are the substances formed as a result of the reaction. Reactants are consumed during the reaction, while products are created from the reactants.
Why are combustion reactions considered exceptions to the rules?
Combustion reactions always include O2 (Oxygen Gas) and a hydrocarbon (hydrogen and carbon) and the products are always CO2 and H2O. So, for example, you have C200H108 + O2 then the products will still be CO2 and H2O. It is considered an exception because normally, in chemical equations, the amount of reactants have to equal the amount of products.
What is the relationship between reactants and products in chemical reactions?
According to the Law of Conservation of Mass, in a chemical reaction, matter is neither created nor destroyed. Because of this the sum of the mass of the reactants will always equal the mass of the products.
Does the total number of atoms stay the same during a chemical reaction?
Indeed by the Law of Conservation of Mass, mass cannot be lost or gained through a reaction. Similarly, atoms cannot be lost, gained or somehow transformed themselves-only rearranged into different compounds. This means there are still going to be the same amount of Hydrogen atoms after a reaction as there were before.
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
What happeneds to atoms in a chemical reaction?
Chemical reactions occur when different atoms and molecules combine together and spit apart. For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs.So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atoms are rearranged as bonds are broken and formed. In all chemical reactions, mass is always conserved...In chemical reactions, atoms rearrenge to form products...During chemical change atoms arrange and form new bonds. The new bonds are form to make the products.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Do Chemical reactions involve the interplay of the electrons of the reacting chemical?
always.
What is the product of synthesis reaction is always what?
The product of a synthesis reaction is always a compound formed from two or more reactants. In these reactions, elements or simpler compounds combine to create a more complex substance. The general formula for a synthesis reaction can be represented as A + B → AB, where A and B are the reactants and AB is the product.

Do chemical reactions always involve changes in energy?
no
In what type of reaction is water always a product?
In hydrolysis reactions, water is always a product. Hydrolysis involves breaking a compound apart by adding a molecule of water.
Does physical state of matter always change during a chemical change?
Not necessarily. Some chemical reactions may change the physical state of matter (e.g. solid to liquid), while others may not involve a change in physical state. It depends on the specific reaction and the properties of the substances involved.
Who invented chemical reactions?
Chemical reactions have always existed in nature. The study and understanding of chemical reactions has evolved over time, with early contributions from alchemists and philosophers, and further developments by scientists such as Antoine Lavoisier and John Dalton. There is no single person who can be credited with "inventing" chemical reactions.
When is a chemical not a chemical?
A chemical is always a chemical, by definition. Chemicals are substances with a distinct structure that can undergo reactions to form new substances.
