Answer:- 5.91%
Solution:- The given balanced equation is:
From given moles of zinc iodide we calculate the moles of zinc carbonate using mol ratio from the balanced equation and the moles are converted to grams on multiplying by molar mass.
=
Molar mass of zinc carbonate is 125.38 gram per mol. Let's multiply the moles by molar mass to get the theoretical yield:
=
theoretical yield is 213.15 g and the actual yield is given as 12.6 g.
percent yield =
percent yield =
= 5.91%
The percent yield of zinc carbonate is 5.91%.
<span>What is the relationship between the atomic numbers and ionic radii of the elements in group 1? What is the relationship between atomic numbers and first ionization energies?
</span>Answer:
When we see down the groups, the atomic number and the atomic radius both increase.Extra shells are produced which increase the size of the higher atoms.
If we go across the periods, the atomic radius decreases due to the higher nuclear charge in the atoms. This pulls the electrons more closer to the nucleus.
Boron fluoride. Since Boron has a 3+ charge, and Fluorine has a 1-, you need 3 atoms of Fluorine and 1 of Boron.
