The correct answer is E. C6H6 is not soluble in water. This is determined by the polarities of these substances. Benzene is a non-polar substance because it has equal number of electrons sharing a bond thus it does not dissolve in water which is a polar substance.
Explanation:

...
Period 4 element.
Hydrogen Rubidium
Strontium
Yttrium
Zirconium
Niobium
Answer:
they gain the few electrons they need to form full octets
Answer:
Explanation:
<u>1) Data:</u>
- T₁ = 25°C = 25 + 273.15 K = 298.15 K
- T₂ = 20°C = 20 + 273.15 K = 293.15 K
<u>2) Formula:</u>
Used combined law of gases:
<u>3) Solution</u>:
Solve the equation for V₂:
Substitute and compuite:
- V₂ = 98.7 KPa × 10.0 L × 293.15 K / (102.7 KPa × 298.15 K)

<span>An atom's identity, that is, whether it is 'oxygen' or 'plutonium', for example, is determined solely by the number of protons in the nucleus. The number of neutrons also plays a part - a differing number of neutrons can change an atom from one isotope of an element into another, but the atoms would still remain the same element, albeit a different isotope. The number of electrons orbiting the atom does not change the identity of the atom, only it's electronic state. Take electrons away and it becomes a positively charged ion of the same element. Add electrons and it becomes a negatively charged ion, but still of the same element.</span>
