The reactant is the chemical reaction of 2 or more different elements.
The product is what is formed in a chemical reaction.
Example: H + O ----> H2O
H + O is the reactants, and H2O is the products.
Answer:
Hydration
Explanation:
In water, ions are surrounded by a sphere of water molecules called a hydration shell. The process of forming this shell is called hydration.
Answer:
the answer is the last option yzxw
Explanation:
ph is stronger the lower
Answer:
D, E, A, B, C
Explanation:
The weakest base would be Cl- because HCl is a stronger acid than that of H3O+ from which the water is formed.
Also, for NH3 is a stronger acid than +NH4. Reason is that oxygen is more electronegative than nitrogen and thus NH3 is a stronger acid than NH4+.
The stronger, the acid, the weaker its conjugate base. Thus, NH3 is a weaker base than NH4.
NH2- has the highest basicity because nitrogen is less of an electronegative element than is oxygen. Therefore, it will not want a negative charge.
Hence, the final order in terms of increasing basicity is;
Cl-, H20, NH3, NH4, NH2-
