Nonmetals form ionic bonds by sharing electrons to complete their valence shell and increase stability.
What number of Fe atoms and what amount (moles) of Fe atoms are in 500.0 g of iron? 500.0 g (1 mol / 55.845 g) = 8.953 mol 8.953 mol (6.023 X 10 23 atoms / 1 mol) = 5.392 X 10 24 36. A diamond contains 5.0 X 10 21 atoms of carbon.
The correct answer is option 2. A 0.8 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than a 0.1 M aqueous solution of NaCl. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: ΔT = -Km and <span>ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.</span>
Answer:
it's the 2 I'm pretty sure
