How do the periodic trends in metallic character compare to those for ionization energy? how do the periodic trends in metallic character compare to those for ionization energy? metals tend to have higher ionization energies than nonmetals. metals tend to have lower ionization energies than nonmetals. metals and nonmetals tend to have the same ionization energies.

Metals tend to have lower ionization energies than nonmetals.

Explanation:

Hello,

Consider the attached picture about periodic trends because it illustrates how ionization energies increase or decrease. As you can see, the higher the metallic character, the lower the ionization energy, thus, metals tend to have lower ionization energies than nonmetals.

Best regards.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
