Answer:

The pressure of argon inside the 155 ml flask is approximately <u>633 mm Hg.</u>

Explanation:

Given:

The temperature is constant. So, the process is isothermal.

Initial pressure of argon is, P_1=785\ mm\ Hg

Initial volume of argon is, V_1=125\ ml

Final volume of argon is, V_2=155\ ml

Final pressure of argon is, P_2=?

Now, as per Boyle's law, for an isothermal process, the product of pressure and volume is always a constant or PV=constant. Therefore, we can write it as:

P_1V_1=constant\\P_2V_2=constant\\\therefore P_1V_1=P_2V_2

Rewriting the above in terms of P_2, we have:

P_2=\frac{P_1V_1}{V_2}

Plug in 785 for P_1, 125 for V_1, 155 for V_2 and solve for P_2. This gives,

P_2=\frac{785\times 125}{155}\\P_2=633.06\approx 633\ mm\ Hg

Therefore, the pressure of argon inside the 155 ml flask is approximately 633 mm Hg.

How can you tell from the name the types of bonds present in a hydrocarbon?
Darya [45]

Answer:

Alkane

Alkene

Alkyne

Explanation:

Alkane=1 bond (Saturated hydrocarbon)

Alkene= 2 bonds (Unsaturated hydrocarbon)

Alkyne= triple bonds (Unsaturated hydrocarbon)

Formula of Alkane = CnH2n+2

Formula of Alkene = CnH2n

Formula of Alkyne = CnH2n-2

Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) P₄(s) → HPO₃²⁻(aq) + PH₃(g) [acidic]
m_a_m_a [10]

The balanced chemical equation is :

5P₄ + 36OH → 12HPO₃⁻² (aq) + 8PH₃ (acidic)

Here the oxidation number of P changed from 0 to -3 in PH₃ and increases  from 0 to +3 in HPO₃⁻². When P₄ changes to PH₃ reduction reaction is taking place as there is addition of hydrogen and when P₄ changes to HPO₃⁻² oxidation takes place as there is addition of oxygen.

Thus clearly both reduction and oxidation are taking place.

Thus, we can infer that here P₄ is both oxidizing as well as reducing agent.

To know more about oxidation number here:
