During her science fair project, mary discovered that solutions of ionic compounds in water conduct electricity. what type of investigation could mary perform to discover which type of ions conduct electricity best?

Mary could do two types of experiments

Type 1. She could hold the cation constant and vary the anion.

She could try solutions of NaCl, NaBr, NaI, Na₂SO₄, Na₃PO₄, etc.

These experiments would tell her which anions are the best conductors.

Type 2. She could hold the anion constant and vary the cation.

She could try solutions of NaNO₃, KNO₃, Mg(NO₃)₂, Ca(NO₃)₂, Al(NO₃)₃, etc.

These experiments would tell her which cations are the best conductors.

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
