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 .
"Pent" is five, "ene" means double bonded carbon
I believe it's the second option. 2 or more elements joined together such that the elements have lost their individual identity in favour of a new set of properties.
In the lake that the rivers lead, water molecules evaporate into the sky and form clouds. In the sky, these water droplets condense and form clouds that will eventually rain.
