A volume of a fixed gas is doubled and the temperature is doubled. What happens to the pressure of the gas?
Montano1993 [528]
We first assume that this gas is an ideal gas where it follows the ideal gas equation. The said equation is expressed as: PV = nRT. From this equation, we can predict the changes in the pressure, volume and temperature. If the volume and the temperature of this gas is doubled, then the pressure still stays the same.

To what final concentration of NH3 must a solution be adjusted to just dissolve 0.060 mol of NiC2O4 (Ksp = 4×10−10) in 1.0 L of
ololo11 [35]
Given:
0.060 mol of NiC2O4
Ksp = 4 x 10⁻¹⁰
1.0 L of solution
Kf of Ni(NH3)6 2⁺ = 1.2 x 10⁹
<span>NiC2O4 + 6NH3 ⇋ Ni(NH3)6 2+ + 2O4 2- </span>
<span>NiC2O4 ⇋ Ni 2+ + C2O4 2- ...Ksp </span>
<span>Ni2+ + 6NH3 ⇋ Ni(NH3)6 2+...Kf </span>

Ksp * Kf = (4 x 10⁻¹⁰) * (1.2 x 10⁹) = 0.48

K = 0.48 = [Ni(NH3)6 2+][C2O4 2-] / [NH3]⁶<span> 
</span>0.48 = (0.060)² / [NH3]⁶<span> ... (dissolved C2O4 2- = 0.060M)

NH3 = ⁶√0.0075 

NH3 = 0.44 M

A balloon filled with air has a volume of 4.24 liters at 23.00°c. if the balloon is cooled at constant pressure to 5.00°c, what
UkoKoshka [18]

The new volume if the balloon is cooled at constant pressure is  3.98 L.

Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.

The new  volume is calculated using the Charles law formula

                                 V₁ / T₁  = V₂ / T₂

where,

V₁ = The initial volume of air = 4.24 l

T₁ = 23.00 °C into kelvin = 23  +273 =296 K

T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K

V₂ = ?

By making  V₂ subject the subject of the formula  by multiplying both sides by T₂

V₂ = ( V₁  × T₂ ) / T₁

V₂ =  (4.24 L  ×  278 K)  / 296 k  

   = 3.98 L

Therefore, the new volume, if the balloon is cooled at constant pressure, is  3.98 L.

An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.
