Which type of reaction releases the most energy Brainly?

Which type of reaction releases the most energy nuclear?

It depends on the atomic number of the element, fusion produces much more energy for lighter elements and fission produces more energy for heavier elements.

Which type of reaction produces the most energy Why?

In energy consuming (endothermic) reactions the total energy of the products is more than that of the reactants – heat is taken from the surrounding substances. The reactions involved in photosynthesis are perhaps the most important of these.

What is the change in energy for reaction A?

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

How do we detect the change in energy?

By comparing the energy used when bonds in the reactants are broken with the energy released when bonds in the products are formed, you can determine whether a chemical reaction releases energy or absorbs energy overall.

Is fusion a chemical reaction?

While chemical reactions – such as the rusting of metal or the burning of wood – involve the redistribution of electrons between atoms, nuclear reactions involve the redistribution of nucleons. … Alternatively, in the proton-proton nuclear fusion reaction, the nuclei of two hydrogen atoms merge together to form helium.

GOOD TO KNOW:  Question: How many solar panels does it take to charge a deep cycle battery?

Why is fusion not currently in use to produce energy?

One of the biggest reasons why we haven’t been able to harness power from fusion is that its energy requirements are unbelievably, terribly high. In order for fusion to occur, you need a temperature of at least 100,000,000 degrees Celsius. That’s slightly more than 6 times the temperature of the Sun’s core.

Why does fusion produce more energy?

In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. … In the process, it also releases much more energy than most fusion reactions.

Where is energy released?

Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
