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>
Answer:
Organisms need to take food to get energy and perform life processes. A living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, circulation of blood, and reproduction. To perform all these life processes the organism needs energy and nutrients.

35 protons which equals 35 electrons but bromine anion with a charge of -1 with one extra electron so 35+1=36 electrons
One experimental property directly related to the strength of intermolecular forces is the boiling point of a substance.
In the liquid state, the intermolecular forces play a large role in the behavior of the substance. If the boiling point is low, this indicates weak forces such as Van der Waal's forces. On the other hand, a high boiling point indicates strong intermolecular forces such as hydrogen bonds.
