Explanation:
the the change is enthalpy is negative, and heat is released to the surroundings.
Answer:
I'm sorry but I'm not doing the whole test
Explanation:
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.

The answer is going to be mercury
CaO because oxygen have 2 dots and calcium as well
(oxygen valency -2
calcium valncy +2)= CaO
