Answer:
Explanation:
NaCl = Na⁺ + Cl⁻
6120 ions of NaCl will contain 3060 ions of Na⁺ and 3060 ions of Cl⁻ , forming 3060 molecules of NaCl .
6.02 x 10²³ molecules of NaCl = 1 mole
3060 molecules of NaCl = 3060 x 10⁻²³ / 6.02 moles
= 508.30 x 10⁻²³ moles
= 5.08 x 10⁻²¹ moles
Answer : 5.08E-21 moles .

Explanation:
When the amount of gas in a container is increased, the volume increases. Lussac's law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
Answer:
Yes.
Explanation:
Because distillation separates substances based on their different boiling points.
Answer:
The principle of superposition states that the oldest rock units are at rock bottom , and therefore the youngest are at the highest . Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
