There are 5 basic types,
Combination Reaction,
Decomposition Reaction,
Displacement Reaction,
Double Displacement Reaction,
Oxidation and Reduction Reaction.
Combination reactions are two substances that combine to form one substance, so think, atoms combining to form molecules, such as H2O (Hydrogen to oxygen, also known as water)
Decomposition reactions are when compounds break down to form 2 or more simpler substances, these usually occur due to heat and energy, so think of water (H20) turning back to hydrogen and oxygen
Displacement reactions are when a higher-energy material displaces a less reactive one from its compound or molecule, so think of high amounts of energy from a material being absorbed by a water molecule, which then breaks down into simpler particles (hydrogen and oxygen)
Double displacement is the same as displacement except that the process happens twice to the same particles.
Oxidation is a chemical reaction where your adding or removing oxygen to a compound. So think of rusting metal (iron oxide)
It speeds up the chemical reactions so most reactions wouldn't happen without water.

Explain why energy is necessary to chemical reactions, and describe some common sources of energy.
In science, reactions occur based on the interactions between different substances or forces. These reactions can result in changes such as chemical reactions, physical changes, or the release of energy. Understanding these reactions is a key aspect of scientific study and can help explain the behavior of matter and energy in the natural world.
Thrse electrons are involved in chemical reactions.
Chemistry is the science who study matter from the point of view of composition, stucture, chemical properties and chemical reactions, synthesis, etc.
Energy is necessary for chemical reactions because it allows molecules to overcome activation energy barriers and initiate reactions. Common sources of energy for chemical reactions include heat, light, electricity, and catalysts. These sources provide the necessary energy to break existing bonds and form new ones during a chemical reaction.
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.
its decomposing ? its kind of hard to explain its like coke and pepsi its the same but it differs its decomposing ? its kind of hard to explain its like coke and pepsi its the same but it differs they are both chemical reactions
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
You have to start with the basics. Students need to understand how atoms are constructed, with positively charged protons in the nucleus, and negatively charged electrons surrounding the nucleus in shells, and they have to understand the electromagnetic forces that result from these positive and negative charges, and then the subject of the stability of electron shells can be raised, with the preference for complete outer shells; with this background, it is then possible to understand how and why chemical reactions take place.
Dalton proposed that a chemical reaction is a rearrangement of atoms because he believed that in chemical reactions, atoms are not created or destroyed, but rather rearranged to form different compounds. This idea helped to explain how different elements combine to form new substances without changing the total number of atoms present.
