Synthesis is when two or more substances combine to form a more complex compound. Decomposition is the opposite process, where a compound breaks down into simpler substances. Endothermic reactions absorb energy, usually in the form of heat, while exothermic reactions release energy in the form of heat.

Physical and chemical changes can be either exothermic or endothermic changes?
The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear. Ray
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
How do you know if an enthalpy change diagram is endothermic or exothermic?
In an endothermic reaction, the products have higher enthalpy than the reactants, leading to a positive overall change in enthalpy. In contrast, in an exothermic reaction, the products have lower enthalpy than the reactants, resulting in a negative overall change in enthalpy. This information can be determined by looking at the direction in which the energy levels are changing on the enthalpy change diagram.
What do you mean by endothermic?
Endothermic - is something that absorbs heat.
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
Are platypus endothermic or exothermic?
Platypuses are endothermic. Platypuses are monotremes, which are egg-laying mammals, and all mammals are endothermic. This means that they regulate their body temperature by internal processes and that their body temperature is constant.
Is baking soda and vinegar an endothermic or exothermic reaction?
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
Is combustion of magnesium reaction with exothermic or endothermic?
The combustion of magnesium is an exothermic reaction because it releases heat energy. The bright white light and high temperatures produced in the reaction are characteristics of exothermic reactions.
Is thermal decomposition a endothermic or exothermic reaction?
Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.

What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
Is burning of wood a endothermic change?
nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
Why let say if the forward reaction is exothermic does this mean that the backward reaction gives out or take in heat and why?
If the forward reaction is exothermic then the back reaction would be endothermic. This happens because it upholds the law of conservation of energy, which says that energy cannot be created or destroyed.
What happens to the heat in a system and in the surroundings in an exothermic reaction?
In an exothermic reaction, heat is released from the system to the surroundings, resulting in a temperature increase in the surroundings. The heat lost by the system is gained by the surroundings, increasing their thermal energy.

In an endothermic reaction, the products have higher enthalpy than the reactants, leading to a positive overall change in enthalpy.

This information can be determined by looking at the direction in which the energy levels are changing on the enthalpy change diagram.
What does 'exothermically' mean?
'Exothermically' refers to a process or reaction that releases energy in the form of heat to its surroundings. It is the opposite of an endothermic process, which absorbs heat from the surroundings.
What is exothermil?
It seems like you're referring to the term "exothermic." Exothermic reactions release heat to their surroundings, resulting in an increase in temperature. This energy release is usually in the form of heat, but it can also manifest as light. Examples of exothermic reactions include combustion and neutralization reactions.
