The types and numbers of atoms at the end of a reaction are the same as before the reaction.

∙ 8y agoAll the atoms that existed at the start of the reaction exist at the end of it. Whether they're "present" depends on how well you've captured all the byproducts of that reaction. If you decide one day to react cellulose from pine trees with oxygen from the atmosphere in a well-known and beloved reaction called "a campfire," a lot of the atoms present in the wood and in the air will become CO, CO2, and soot, and float away. They still exist, but unless you can capture all the smoke and hold it in a container, they're no longer present.

∙ 8y agoThe same number of elements that are at the start of a reaction are the same number at the end. You are balancing element numbers with the equations you are doing.

What does it mean to balance a formula?
To add atoms into a formula so that a chemical reaction will end with the same amount of atoms from the beginning. Ex. CH4 + 2O2 --> CO2 + 2H2O The law of conservation of mass states that matter cannot be created or destroyed, so if you end with CO2, all other atoms that were present before the reaction must also be present in the "after" formula; you have to add to either side so that there will be the same amount of atoms on both sides.
What do you know about types of atoms before and after a reaction?
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
If a reaction starts with a 6 atoms of a solid and 12 atoms of a gas what is known about the product?
They will contain 18 atoms total in all the products.

Which intermolecular force is present in all molecules and atoms?
Dispersion.
How can you say that electrons are present in all types of matter?
All matter is made up of atoms, all atoms have electrons that orbit the nucleus.
What is a positively charged particle that is present in all atoms called?
ion
How does the burning of hydrocarbons release energy?
The carbon and hydrogen present in the fuel react with the oxygen that taken inside cylinder during induction and the explosion takes place.
Atoms can disappear completely in some chemical reactions-true or false?
false. atoms can either be fused or defused in all chemical reaction.
