Balance Chemical equation is,
P₄ + 10 Cl₂ → 4 PCl₅
According to Balance Equation,
123.89 g (1 mole) of P₄ reacts to produce = 4 Moles of PCl₅
Then,
23 g of P₄ will react with excess Cl₂ to produce = X moles of PCl₅
Solving for X,
X = (4 mol × 23 g) ÷ 123.89 g
X = 0.742 g of PCl₅
Result:
When 23 g of P₄ is reacted with excess Cl₂, 0.742 g of PCl₅ is produced.
K2 SO4 = 2[K+] + [SO4 2-]
Which means that every mol of K2SO4 gives 3 moles of ions.
Then 1.25 mol of K2SO4 gives 3*1.25 = 3.75 moles of ions.
Answer: 3.75
Answer: Yes it is. Rust would be considered a chemical reaction because it changes the chemical makeup of the metal.
