Answer:
The answer is below
Explanation:
Here some of the difference between aluminum phosphide and aluminum phosphate
1. Aluminum phosphide is a crystalline solid with either dark gray or yellow color. While Aluminum Phosphate is in a nanopowder form but with a whitish color.
2. Aluminum phosphide is used in the fumigation of plants, while Aluminum phosphate is used in cosmetics, paints, etc.
3. Aluminum phosphide has a compound formula of AlP with a molar mass of 57.9552 g/mol, while Aluminum Phosphate has a compound formula of AlO4P with a molar mass of 121.9529 g/mol

106 g Na</span>₂CO₃ -------- 2 x 36.5 g HCl
<span> x g Na</span>₂CO₃ ---------- 750 g HCl
<span>
Mass of Na</span>₂CO₃ = 750 x 106 / 2 x 36.5
<span>
Mass ( Na</span>₂CO₃) = 79500 / 73

Mass = 1089.04 g
Number of moles = 1089.04 / 106 => 10.27 mols of Na</span>₂CO₃

Answer:
AgCl
Explanation:
The reaction of KCl (In aqueous phase K⁺ + Cl⁻) with AgNO₃ ((In aqueous phase Ag⁺ + NO₃⁻) produce:
Ag⁺ + Cl⁻ ⇄ AgCl(s)
The reaction has a k of 5.56x10¹⁰
That means you will produce 5.56x10¹⁰ molecules of AgCl per molecule of Ag⁺ and Cl⁻ in solution.
As the AgCl is in solid state, this molecules is the precipitate.

Answer:
P₂ = 0.87 atm
Explanation:
Given data:
Initial pressure = 1.10 atm
Initial volume = 19.2 L
Final volume = 24.3 L
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.10 atm × 19.2 L = P₂ × 24.3 L
P₂ = 21.12 atm. L/ 24.3 L
P₂ = 0.87 atm
