Answer: The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.

Answer:
Density = 0.0035 g/cm³
Explanation:
The density equation looks like this:
Density (g/cm³) = mass (g) / volume (cm³)
You have been given both the mass and volume. However, the given volume is not in the correct units. To convert cm to cm³, you should simply raise the given volume to the power of 3.
24 cm = (24 cm)³ = 24³cm³ = 13,834 cm³
Now, you can plug you mass and volume into the equation and solve for density. The final answer should have 2 sig figs to reflect the given values.
Density = mass / volume
Density = 48 g / 13,824 cm³
Density = 0.00347 g/cm³
Density = 0.0035 g/cm³
Answer:
less neutral
Explanation:
A solution with pH 5 is less neutral than a solution with pH 7 because pH 5 is acid
