Answer:
<u>In this reaction heat is released</u>
Explanation:
Exothemic Reactions : Those reactions in which heat is released when the products are formed .
For such reaction The enthalpy change is negative.
for exothermic reaction
Endothermic Reactions : Those reaction which proceed by absorbing heat . Here heat is absorbed. The enthalpy change for such reactions is positive.
When the direction of reaction reverses , the value of H also changes.
In the given reaction,
= heat is absorbed
So,
= heat is<u> released</u>
<u></u>
<u>E</u><em>xothermic reactions are more spontaneous as compared to endothermic ractions. This means that they proceed own their own . Only little amount of energy is supplied to exothermic reaction to produce the prodct.</em>

Explanation:
The answer is 2 electrons.
The electron configuration of calcium is 2:8:8:2
Calcium has two electrons in its outermost shell. These are its valence electrons and are the ones used in bonding with other elements. Valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding.
Calcium is a metal. When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms forming ions. The resulting compound is known as an ionic compound.
For example, when calcium metal reacts with chlorine gas, calcium gives up its two valence electrons and Chlorine accepts them resulting in a new substance called calcium chloride in which the two elements have ended up forming ionic bonds.
