M=D*V
D=10.5 g/cm³
V=42.5 cm³
m= 10.5 g/cm³ * 42.5 cm³ ≈ 446 g
m≈446 g
The electron configuration of a calcium ATOM would be
But, the calcium ION has two electrons less than a calcium atom.
The electron configuration of a calcium ION should be the same as Argon since a calcium ion is missing 2 electrons.
Your answer is
Have an awesome day! :)
Answer: <span>B. a nonpolar molecule
</span>Water is a molecule made of two hydrogens and one oxygen. Water structure looks like a mickey mouse which makes it polar.
A polar compound will attract others polar molecules. That cause a polar substance will have much more solubility in water than non-polar substance like oil. Since the substance is not dissolved in water, it is more likely for it to be a non-polar molecule.
