Answer:
This is an endothermic reaction with a positive ΔHrxn.
Explanation:
From the question given above, we can see clearly that the energy of the product (Hp) is greater than the energy of the reactant (Hr). This simply means that the reaction is endothermic as the enthalpy change (ΔH) for the reaction will be positive.
Enthalpy change (ΔH) = Heat of product (Hp) – Heat of reactant (Hr)
ΔH = Hp – Hr = positive
NOTE: A reaction with positive enthalphy change (ΔH) is termed endothermic reaction.
Answer and Explanation:
DIFFERENCE BETWEEN ELEMENT AND COMPOUND :
- An element is made up of same type of atoms whereas a compound is made up of different type of atoms.
- A compound can be separated by chemical methods but an element can not be separated by chemical methods.
- Example of element is Cu Fe C and example of compound is
etc - Elements can not be split into different substances but compound can be splited into different substances
The answer is C. <span>The density of the fluid is greater than the density of the object.</span>
Because the alkali metals are the group 1 metals, they have only 1 valence electron that they want to lose, and the halogens are the group 17 nonmetals, they want to gain 1 valence electron to become stable.
