Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
<h3>What affects the rate of nuclear reactions?</h3>
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
<h3>What is the main difference between chemical reactions and nuclear reactions?</h3>
Chemical reaction normally occurs outside the nucleus. Nuclear reaction happens only inside the nucleus. When chemical reactions occur elements hold their identity and the nuclei of atoms also remains unchanged. During nuclear reactions, the nuclei of atoms changes completely and new elements are formed.

Answer:
Mantle
Explanation:
Convection currents in the Earth occur in the mantle. The core of the Earth is extremely hot, and material in the mantle close to the core is heated...
Hope that help <3
Answer:
Boiling - when the liquid is heated to a gas.
Evaporating - when the air temperature is hotter than the surface of the liquid so the water turns into water vapor or a gas.

Answer:
oxygen, water and sugar are the out come of photosynthesis
Magnesium nitrate o not react with magnesium sulfate because it cannot displace the ions involved. The cations are the same so they just cancel the charges. If you look at it, even of a reaction occurs the product will still be the same substances.
