Explanation:
The answer would be<span>:
B</span>. <span>It is positive because the enthalpy of the products is greater than the enthalpy of the reactants.
The endothermic reaction has a positive enthalpy change because it absorbs the energy of the system. Since the product of the reaction has a greater enthalpy than the reactant, the reaction needs to take the extra energy from the system. Since the system losing energy, the surrounding temperature will drop.</span>
Answer: Knowledge attained through study or practice. Or uses observation and experimentation to describe and explain a natural phenomena.
<span>
some elements have their outer electrons more tightly bound than
others. Those who have less tightly bound electrons are more reactive.
After this it gets more complex in explaining why they are bound with
different strengths. </span>
