Less compassionate around the chocolate
An element is composed of a single type of cell. So we can expect only one kind of element. For example if it is a carbon element it will contain only carbon atoms.
Answer:
Explanation:
The water molecules move around the salt ions
In water, the salt separates into positive and negative ions.
The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction.
<h3>What is an Exothermic reaction?</h3>
An Exothermic reaction in thermodynamics is a type of reaction that released energy from the system of reaction to it's surroundings which can be inform of light, heat or even electricity or sound.
Exothermic reaction has net negative standard enthalpy change.
Therefore, The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction
