The radii of most atoms are actually measured in the Ǻ, or Angstrom. We can do it in nanometers too, however.
<span>First, we take the radius of the smallest atom, He (Helium). Atomic radius = .031 nm. The largest atom, stable atom is Fr (Francium), with atomic radius = .27 nm. </span>
<span>Therefore, the typical atomic radius is between .031 and .27 nm.</span>
(1) Give the formula and name for the iconic compounds formed from the following pairs of elements:

B. MgSO₄ magnesium sulfate
C. KNO₃ potassium nitrate
(3) Give the name of the following covalent compounds:
A. SO₂ sulfur dioxide

D. SCl₂ sulfur dichloride
Moles= molarity x liter
=0.2500 M x 0.500 L
= 0.1250 mol
mass C2H2O4 . 2H2O = 0.1250 mol x (126.068 g / 1 mol)
=15.76 g
Answer:
Using the graph, we can see that after 4.5 minutes, the bus traveled 4500 meters. Find 4.5 on the x axis, and then see what y value it corresponds to.
Let me know if this helps!
