Answer: 38.6 ml

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.


V\propto T    (At constant pressure and number of moles)

\frac{V_1}{T_1}=\frac{V_2}{T_2}

V_1= initial volume = 17 ml

V_2= final volume = ?

T_1= initial temperature =-122^0C=273+(-122)=151K

T_2=final temperature=70^0C= 70+273=343K

\frac{17}{151}=\frac{V_2}{343}

V_2=38.6ml

Thus final volume is 38.6 ml at 70^0C

If the concentration of Mg2+ in the solution were 0.039 M, what minimum [OH−] triggers precipitation of the Mg2+ ion? (Ksp=2.06×
Elodia [21]

Answer:

2.30 × 10⁻⁶ M

Explanation:

Step 1: Given data

Concentration of Mg²⁺ ([Mg²⁺]): 0.039 M

Solubility product constant of Mg(OH)₂ (Ksp): 2.06 × 10⁻¹³

Step 2: Write the reaction for the solution of Mg(OH)₂

Mg(OH)₂(s) ⇄ Mg²⁺(aq) + 2 OH⁻(aq)

Step 3: Calculate the minimum [OH⁻] required to trigger the precipitation of Mg²⁺ as Mg(OH)₂

We will use the following expression.

Ksp = 2.06 × 10⁻¹³ = [Mg²⁺] × [OH⁻]²

[OH⁻] = 2.30 × 10⁻⁶ M

Which type of seismic waves produces the most severe ground movement?
Leto [7]
The surface waves are the type of seismic waves that produce the most severe ground movement. This wave is slow in nature and so produces a rolling effect similar to a surface wave in a pond. This kind of wave is far more devastating than the P waves and the S waves. The surface waves have the capacity to shake a building from side to side until it collapses. This kind of wave moves in a pattern similar to a circle. It actually originates at a point and then start moving outwards in a circle.
