What else can I help you with?
What do you call a change that makes new substances?
Chemical
What do you call the substances before a chemical reaction takes place?
These initial substances are the reactants.
What do you call simple bodies which enter originally into the composition of mixtures?
The simple bodies that enter originally into the composition of mixtures are called elements. Elements are substances that cannot be broken down into simpler substances by chemical means and are the building blocks of all matter.
How you call the starting substances that are evolved in a chemical reaction?
Reactants.
What do you call substances that are made by a chemical reaction?
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
What do we call the substances present before a chemical change?
The substances present before a chemical change are called reactants. They undergo a transformation during the chemical reaction to form new substances known as products. Reactants are crucial in determining the outcome of the reaction based on their chemical properties and interactions.
Is ability to react with other substances chemical or physical?
The ability for a substance to react with other substances is a chemical property, as it involves changes in the substance's chemical composition. Physical properties, on the other hand, relate to characteristics such as color, shape, and state of matter, which do not involve changes in chemical composition.
What do you call a chemical reaction in witch a complex substance is broken down into simpler substances?
decomposition
What do you call pure substances formed from chemical combinations of two or more different elements?
By 'chemical combination' I assume you mean that the Elements have reacted with one another.If they have reacted, the result would be called a Compound (or the Product) and, the input Chemicals are called Reactants.
What do you call the substaces before a chemical reaction takes place?
The initial substances in a reaction are called reactants.
What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
What do they call the compounds to the left of the arrow in a chemical reaction?
The compounds to the left of the arrow in a chemical reaction are called reactants. They are the starting materials that undergo a chemical change to form new substances.
