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.
How can a decomposition reaction help you determine whether a pure substance is an element or a compound?
A decomposition reaction breaks down a compound into its elemental constituents. By analyzing the products of the reaction, you can determine if the original substance was a compound (multiple elements present) or an element (only one type of element present).
How many chloride ions are present?
The number of chloride ions present in a given substance depends on the substance size and the type of substance.
A chemical reaction begins with a substance called and ends with substance called?
Pure substances (or ELEMENTS) form COMPOUNDS after a chemical reaction. For example: Sodium and chlorine, when fused in a chemical reaction become the compound Sodium-Chloride The substance you have in the beginning of a chemical reaction are called reactants and the substance you have when chemical reaction is complete is called products.
A substance that undergoes change in a chemical reaction is called a what?
A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.
What is a substance that enters into a chemical reaction called.?
The reactant is the substance present at the start of a chemical reaction, while the product is the substance(s) formed from a chemical reaction.
Is it trueThe substance that are present when a chemical reaction begins are the products?
No: the substances present at the beginning of reaction are the reactants or reagents.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is a chemical reactants and the products in the reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
What are the substance you start with in a chemical reaction?
The reactants
What is a substance that results in a chemical change called?
A substance that results in a chemical change is called a reactant. Reactants are substances that are present at the start of a chemical reaction and are transformed into different substances (products) during the reaction.
Is it true that if the substance that are present when a chemical reaction begins are the products?
true
What is a substance that are present after the reaction has taken place?
These substances are called products.
What are the substance that are present after the reaction has taken place?
These substances are called products.
What term describes a substance that lowers the energy needed to start a chemical reaction?
This substance is a catalyst.
