A saturated is one in which the atoms are linked by single bonds. :)
Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed.</span>
Answer:
The two ions would be Na: Sodium and Cl: Chloride.
The answer is A- single bonds made by 1 atom to 3 other atoms within a molecule
