What else can I help you with?
What is the same number that existed before the reaction exist after the reaction?
The total number of atoms is conserved in a chemical reaction, meaning the number of atoms of each element before the reaction will be the same as after the reaction. This principle is known as the law of conservation of mass.
What does not increase the number of particles of a substance available to react in a chemical reaction?
A change in state (solid to liquid) does not increase the number of particles available to react because the same number of particles are still present in the substance.
True or False chemical reaction occurs at the same rate no matter what size of the reactant particles?
False. The rate of a chemical reaction can be influenced by the size of the reactant particles. Smaller particles have a larger surface area, allowing for more frequent collisions between particles and therefore potentially increasing the rate of reaction.
Why does the number of atoms and twist ties have to stay the same?
In a chemical reaction, the total number of atoms before and after the reaction must remain the same according to the law of conservation of mass. This principle ensures that no atoms are gained or lost during a reaction. Similarly, in a twist tie puzzle, the number of twist ties must stay the same to maintain the challenge and difficulty of the puzzle.
What remain unchanged in a chemical reaction?
In a chemical reaction, the total number of atoms of each element remains the same before and after the reaction. This is known as the law of conservation of mass. Additionally, the total charge in the reaction should also remain the same.
What happens to the number of particles at the beginning and end of the iron and sulfur reaction?
In a reaction between iron and sulfur to form iron sulfide, the total number of particles remains the same before and after the reaction. This is due to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
Can you increase the number of particles of a substance in a chemical reaction?
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.

A change in state (solid to liquid) does not increase the number of particles available to react because the same number of particles are still present in the substance.
When double replacement reactions in aqueous solution produce water the number of solvent particles decrease?
Yes, that's correct. In a double replacement reaction where water is produced, the total number of solute particles remains the same, but the number of solvent particles (water molecules) decreases because some of them are consumed in the reaction to form the product.
What particles change in chamical change?
In a chemical change, the particles that change are atoms and molecules. Bonds between atoms break and form new connections, leading to the formation of different substances with unique chemical properties. The number and type of atoms remain the same before and after the reaction, but their arrangement and bonding change.
The atomic number is the same number as the number of these particles?
protons

The atomic number is the same as the numberof these particles?
The number of electrons
Is the number of gas particles the same as moles?
No
Do the compounds remain the same as before the reaction when a chemical reaction occurs?
true
