At a certain temperature, the solubility of strontium arsenate, sr3(aso4)2, is 0.0480 g/l. what is the ksp of this salt at this
Nadusha1986 [10]
Given the solubility of strontium arsenate is 0.0480 g/l . we have to convert it into mol/L by dividing it over molar mass (540.7 g/mol)
Molar solubility = 0.0480 / 540.7 = 8.9 x 10⁻⁵ mol/L
Dissociation equation:
Sr₃(AsO₄)₂(s) → 3 Sr²⁺(aq) + 2 AsO₄³⁻(aq)
                             3 s                   2 s
Ksp = [Sr²⁺]³ [AsO₄³⁻]²
       = (3s)³ (2s)²
       = 108 s⁵
Ksp = 108 (8.9 x 10⁻⁵) = 5.95 x 10⁻¹⁹

A rook is dropped into a graduated cylinder filled with 35 mL of water.
KonstantinChe [14]

Answer:

5 cm³.

Explanation:

The following data were obtained from the question:

Volume of water = 35 mL

Volume of water + Rock = 40 mL

Volume of rock =.?

The volume of the rock can be obtained as follow:

Volume of rock = (Volume of water + Rock) – (Volume of water)

Volume of rock = 40 – 35

Volume of rock = 5 mL

Finally, we shall convert 5 mL to cm³. This can be obtained as illustrated below:

1 mL = 1 cm³

Therefore,

5 mL = 5 cm³

Thus, the volume of the rock is 5 cm³.

What happens during a phase change from a solid to a liquid?
JulijaS [17]

Answer:

The particles of the solid vibrate faster and faster. After a while, they can start to move around

Explanation: Solid particles movement are restricted due to the strong force of attraction between the molecules,Solid phase will only change to liquid phase if the forces of attraction holding the molecules together are broken down by heat, when this happens the solid particles movement will become more mobile as the substance is moving from solid phase and liquid phase
