What happens when you pour acid on marble?
You will see bubbles and during this reaction, the solid dissolves and CO2 is released
How can we increase the speed of a collision?
Increasing the temperature, splitting the substance into smaller pieces
What are the substances called formed in chemical reactions?
products
Name 3 chemcial reactions ( not in your book )
hopefully good job
In a chemcial reaction, what happens to the molecules of the reactants?
they are destroyed
What happens to the atoms of the reactants in a chemical reaction?
They regroup to form new molcules (but first they need to collide)
What happenes in collision theory?
chemical reactions are produced when the particles of the reactants collide with each other and are broken. The loose atoms rearrange themselves.
What is conserved in a chemical reaction?
the atoms involved and the mass
What changes in a chemcial reaction?
the chemical formula of the substance and the number of molecules (sometimes)
According to Antoine-Laurent Lavoisier, what stays the same?
mass
A chemical reaction is the process of converting _____ to _____.
reactants to products
A collsion is only effective if _____?
the molecules collide at the right orientation and speed
In the formation of hydrochloric acid, what has to happen in order to form the H-Cl molecule?
the Cl-Cl molecules and the H-H molecules must first be broken
What is very important in determining weather or not a reaction occurs?
The speed of particles
