Explanation:
Hello!
In this case, since the percentage by mass of a solute in a solvent is computed as shown below:
Now, as the solute here is calcium chloride and has a mass of 35.0 g and the solvent is water with a mass of 425.0 g, we can compute the percentage by mass as shown below:
Best regards!
The correct answer is D. Elements are created that differ from the reactants.. Because in a eeaction, the product is different than the reactants. Take NaCl for example.
Answer:
the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.
