Dehydration synthesis, also called condensation, is the type of reaction that builds polymers by removing water.
Dehydration Synthesis
chemical
A reaction between two substances or the decomposition of a substance are chemical changes.
Monomers.
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
hydrolysis
they bond together
This is a chemical decomposition reaction.
it is when a reaction occurs and elements are "taken" apart and put in a new order to create a new substance.
This is a chemical reaction because it is not possible to rearrange water and oxygen to form hydrogen peroxide after they are split apart (in other words after the chemical reaction has occurred. (And this was also part of the question in my homework so to make it easier Hydrogen peroxide is the reactant, and oxygen and hydrogen are the products.)
chemical bond
Energy is absorbed, hence it is an endothermic process. The two atoms shared energy. Breaking them apart means they need energy replaced, which is taken from atmospheric heat.
Decompisition reaction
chemical
2HgO → 2Hg + O2 Mercury (II) oxide → Mercury (II) + Oxygen
Depending on the polymer, possibly nothing, possibly the polymer would break apart.
A reaction between two substances or the decomposition of a substance are chemical changes.
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
