What else can I help you with?
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
What must combined to create a chemical equation?
Reactants and products must be combined to create a chemical equation. Reactants are the starting materials that undergo a chemical reaction, while products are the substances that are formed as a result of the reaction.
What must be produced in a chemical reaction to result in a chemical esplosion?
Usually a reaction must produce some sort of gas to be explosive.
What must energy do to break achemical bonds for a reaction to occur?
Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.
What is the primary reason why chemical bonds form?
for energy:) The major reason for chemical bonding is to produce energy. As a reaction occurs and begins to form products at a lower energy, energy must be released.
What must happen for new substances to be produced?
To obtain new substances a chemical reaction is needed.
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
What must combined to create a chemical equation?
Reactants and products must be combined to create a chemical equation. Reactants are the starting materials that undergo a chemical reaction, while products are the substances that are formed as a result of the reaction.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
Is the ability to react with other substances a physical property or a chemical property?
The ability to react with other substances is a chemical property because it describes how a substance interacts with other materials to form new substances with different properties. It is related to the substance's chemical composition and behavior in chemical reactions.
Definition of chemical reaction?
A chemical reaction is a process that involves the rearrangement of atoms in molecules to form new substances with different properties. This typically involves breaking existing chemical bonds and forming new ones. It is governed by the law of conservation of mass, meaning that the total mass of the reactants must equal the total mass of the products.
Why would reactants at the beginning of a chemical reaction weigh the same as the product at the end?
In a chemical reaction, atoms are rearranged to form new substances. The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction, so the total mass of reactants must be equal to the total mass of products. Therefore, the mass of the reactants at the beginning of a reaction is the same as the mass of the products at the end.
Must new substances form when you observe a chemical property?
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
Why do reactants in a chemical reaction weigh exactly the same as different products at the end of a reaction?
Energy may only be transformed from one sort to another. Mass is a form of Energy and as such, must be, and is, conserved. It is 'of no surprise' then, that the number of atoms that enter a chemical reaction is equal to the number of atoms that exist after the reaction has been completed.
What energy is needed to start a chemical reaction?
Activation energy is the energy needed to start a chemical reaction by breaking the existing chemical bonds in the reactants before new bonds can form in the products. This energy barrier must be overcome for the reaction to proceed.
What must be produced in a chemical reaction to result in a chemical esplosion?
Usually a reaction must produce some sort of gas to be explosive.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
