What must happen for a chemical reaction to happen?
In order for a chemical reaction to take place, the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed.
What causes a chemical reaction to occur?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

What is chemical reaction answer?
Chemical reaction is a process in which one or more substances i.e. the reactants, are converted to one or more different substances i.e. the products. Example: Hydrogen + oxygen—-> Water.
What is a chemical reaction quizlet?
chemical reaction. A process in which one or more substances (reactants) are changed into one or more other substances (products). the law of conservation of mass. In a chemical reaction, the starting mass of the reactants equals the final mass of all products. Matter is neither created nor destroyed.
Which of the following may occur during a chemical reaction?
In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Which of the following occur during a chemical reaction?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What begins a chemical reaction?
These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
What happens during a chemical reaction quizlet?
In chemical reactions, atoms rearrange to form one or more different substances. In a chemical change, the properties that give a substance its identity change. Chemical equations show that in chemical reactions, atoms rearrange, but no atoms are lost or gained.
How do you know if a chemical reaction occurs?
How can I tell if a chemical reaction is occurring? A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change.

Which of the following determines the occurrence of a chemical reaction?
Some signs that a chemical change occurred include temperature increase, spontaneous change in color after mixing compounds, a marked odor after the reaction begins, formation of a precipitate in the solution and release of bubbles.

What is chemical reaction explain with an example?
A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.
What are the main characteristics of chemical reaction?
The characteristics of a chemical reaction are :
- Evolution of gas.
- Formation of a precipitate.
- Change in color.
- Change in temperature.
- Change in state.
- Formation of new substances.
What is meant chemical reaction?
Chemical Reaction: – The processes, in which a substance or substances undergo a chemical change to produce new substance or substances, with entire new properties,are known as chemical reactions. The nature and identity of products totally different from the reactants. Chemistry.
Which of the following determines the occurrence of chemical reaction?

What 3 characteristics must a chemical equation have?
The 3 characteristics of balanced equation is :
- We can get equal no. of atoms on both the sides.
- weight of products and reactants remains constant.
- Desired stoichiometry of the reactant and product is determined to calculate the required amount of reactant and desired result of product.
