Yes, it is true: all chemical reactions create new molecules of compounds.
A chemical reaction imply minimum two reactants (chemical compounds), to obtain the final products.
Enzymes, both outside and inside the cell, are molecules (usually proteins) that enable food to be broken down (although they do not perform this reaction directly).
chemical bonding
Yes…all matter is composed of particles (electrons, nuclei, protons). Together, these particles create atoms. Atoms create molecules and compounds. Since molecules and compounds are matter and eyes are matter, eyes are made up of atoms and molecules.
Elements form together to create compounds such as H2O-water it is just two hydrogen and one oxygen. This is also known as dihydrogenmonoxide (said- di...hydrogen...mon..oxide), without this coumpound there would be no living oranisms
They are both "Chemically joined" so True :3

chemical bonding
The suns heat is a catalyst for a chemical reaction that bleaches. Molecules in air combine to create an oxidizing reaction, like hydrogen peroxide.
Stars do not carry out a chemical reaction; they carry out a thermonuclear reaction. Instead of chemicals reactiing to form new compounds, hydrogen atoms fuse together to formm helium. This process releases far more energy than any chemical reaction.
Matter is simply rearranged, atoms are exchanged to create new molecules.
chemical
In chemical reactions, the number of atoms stays the same, yet they may recombine into different types of molecules. That is why some chemical reactions use two compounds to create a different coumpound.
No.
Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.Yes, whenever a candle burns, it is a combustion reaction between the carbon compounds of the wick and wax of the candle and of oxygen in the air. These compounds burn to create carbon dioxide and water, and also a few smaller carbon compounds, which is evident as the smoke rising occasionally from the flame. The flame you see and the heat you feel rising off of the burning wick is the evidence of an exothermic chemical reaction.Yes, burning a candle is a chemical reaction.
