Answer:
True
Step-by-step explanation:
An ionic bond is the attraction between a cation and an anion.
If there is no cation or anion, there is no ionic bond.
2Al + 3CuCl2 ➡ 2AlCl3 + 3Cu.
Moles of Al = 1.2/27 = 0.045 moles
2 moles of Al reacts with 3 moles of CuCl2.
Therefore, 1 mole of CuCl2 reacts with =2/3 x moles of Al
= 2/3 x 0.045
= 0.03 moles.

Moles of Lithium phosphate : 0.495
<h3>Further explanation</h3>
Given
6 Li + Zn₃(PO₄)₂ ------- > 2 Li₃PO₄ + 3 Zn
Required
Moles of Lithium phosphate
Solution
moles of Zinc(Ar=65,38 g/mol) :
= mass : Ar
= 48.6 : 65.38
= 0.743
From equation, mol ratio of Zn : Li₃PO₄ = 3 : 2, so mol Li₃PO₄ :
= 2/3 x mol Zn
= 2/3 x 0.743
= 0.495
Answer:
Lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing? The energy of the molecules in the ground decreases.
