D except for the transition metals copper iron tantalum etc they have different oxidation states so arent fixed shells but all main group elements are grouped by the valence electrons sodium potassium lithium alkali column 1 valence electron highly reactive.
Answer:
Explanation:
Hello,
In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:
Thus, we can compute the percentage of ionic character by:
So the fraction is just:
Which has sense since gallium phosphide is a non-polar compound.
Regards.
Answer:
Volume of water at this temperature is 27.2 mL
Explanation:
We know that
Here density of water is 0.992 g/mL
Here mass of water is 27.0 g
So
=
= 27.2 mL
Three grams per liter times five liters tells us that there are fifteen grams of salt in this five liter solution.
