In a chemical reaction bonds are broken and then reformed in a different arrangement. If the reaction is exothermic, this is because the new bonds are at a lower energy level than the old ones. For example, if you burn methane in oxygen, you are breaking C-H and O-O bonds and forming C=O and H-O bonds. If you look up(in a data table) the bond energies of each of the bonds you can total up the energies of the reactants (methane and oxygen) and products (carbon dioxide and water), and you will find that there is less energy in the bonds at the end than at the beginning. That's the energy that is released as heat.
What else can I help you with?
Do covalent bonds give water a low heat capacity?
No, covalent bonds do not directly contribute to water's high heat capacity. Water's high heat capacity is due to its ability to form hydrogen bonds, which allow it to absorb and release heat energy without changing temperature significantly. These hydrogen bonds are formed between water molecules, which have polar covalent bonds.
Is gold a covalent bond?
Covalent bonds are usually between a non-metal and another non-metal. Ionic bonds are usually between a metal and a non-metal. Since gold is a metal it will make ionic bonds not covalent.
Is Platinum ionic covalent or metallic?
Platinum is a transition metal, so it exhibits metallic bonding. It forms metallic bonds between its atoms, which allows it to conduct electricity and heat well.
Does covalent bonds give water a low heat capacity?
No, covalent bonds do not directly affect water's heat capacity. Water's high heat capacity is due to its hydrogen bonds, which allow for a large amount of heat to be absorbed or released without causing a large temperature change.
Does metal have ionic covalent or metallic bonds?
When metals bond together, those are called metallic bonds. When they bond with nonmetals, they are called ionic bonds.
DOES Fullerene conduct heat?
Yes, each carbon forms 3 covalent bonds leaving free electrons that can conduct electricity!

What materials conduct heat and which do no?
the materials like metal(which have free electrons) conduct heat and light both and those materials which are formed by covalent bond (do not have free electrons) generaly non metals do not conduct heat and electricity.
What input is necessary for the breaking of covalent bonds, which requires the input of energy?
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
What is a characteristic of a covalent solid?
A characteristic of a covalent solid is that it consists of atoms or molecules held together by covalent bonds. These solids typically have high melting and boiling points due to the strong bonds between the atoms or molecules. Covalent solids are typically hard and have low conductivity of electricity and heat.
Why are covalent compounds poor at conducting heat?
Covalent compounds have strong intramolecular bonds but weak intermolecular forces, making them poor conductors of heat. Heat is transferred through the vibration of atoms, and in covalent compounds, heat energy is mostly trapped within the molecule rather than being conducted through the material.
What are some properties of covalent crystals?
Covalent crystals have strong covalent bonds between atoms, resulting in a hard and brittle structure. They have high melting and boiling points due to the strong bonds that hold the structure together. Covalent crystals are typically insulators and have low conductivity of heat and electricity.
Is ice metallic or nonmetallic?
Ice is nonmetallic. It is a solid form of water, which is composed of covalent bonds between hydrogen and oxygen atoms. Metals, on the other hand, typically have metallic bonds that allow them to conduct electricity and heat.
