7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.
<h3>What are moles?</h3>A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:

Moles of 7.5 g of lithium phosphate.
The molar mass of lithium phosphate is 115.79 g/mol.
Moles =
Moles =
Moles =
Moles = 0.06477243285
Now we will compare the moles of with
.
:
2 : 2
0.385 : 2÷2× 0.064 = 0.064 mol
Mass of :
Mass of = moles × molar mass
Mass of =0.064 mol × 121.9529 g/mol
Mass of = 7.8049856 g
Hence, 7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.

Answer:
Explanation:
In this problem,
we will determine the enthalpy at the end of heat input and we get the condition is the super heated state.
so the entropy change will be due to latent heat at 150 kPa and also due to temperature change at the super heated state.
All the temperature, enthalpy is evaluated with the help of the steam table.
mass is calculated with the help of a specific volume at initial condition.

3) 2AgCl → 2Ag + Cl₂
<u>Explanation:</u>
2)
Step 1: Crushing & Grinding CuFeS₂(s)→ CuFeS₂(s)
Step 2: Froth Flotation CuFeS₂(s)----> CuFeS₂ (l)
Step 3: Roasting 2CuFeS₂(l) + 3O₂(g) → 2FeO(s) + 2CuS(s) + 2SO₂(g)
Step 4: Converting matte to blister Cu₂S(l) + O₂(g) → 2Cu(l) + SO₂(g)
Step 5: Anode Casting Cu(l) → Cu(s)
Step 6: Electrolytic Refining Cu(s) → Cu(s)
Anode: Cu(s) → Cu₂ + (aq) + 2e-
Cathode: Cu2 + (aq) + 2e- → Cu(s)

3) When silver chloride (solid) is exposed to sunlight, it decomposes into silver (solid) and chlorine (gas).
The equation is written as:
