Answer: 600 mL
Explanation:
Given that;
M₁ = 5.85 m
M₂ = 1.95 m
V₁ = 200 mL
V₂ = ?
Now from the dilution law;
M₁V₁ = M₂V₂
so we substitute
5.85 × 200 = 1.95 × V₂
1170 = 1.95V₂
V₂ = 1170 / 1.95
V₂ = 600 mL
Therefore final volume is 600 mL
Answer : The value of
at this temperature is 66.7
Explanation : Given,
Pressure of
at equilibrium = 0.348 atm
Pressure of
at equilibrium = 0.441 atm
Pressure of
at equilibrium = 10.24 atm
The balanced equilibrium reaction is,
![PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)](https://tex.z-dn.net/?f=PCl_3%28g%29%2BCl_2%28g%29%5Crightleftharpoons%20PCl_5%28g%29)
The expression of equilibrium constant
for the reaction will be:
![K_p=\frac{(p_{PCl_5})}{(p_{PCl_3})(p_{Cl_2})}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%28p_%7BPCl_5%7D%29%7D%7B%28p_%7BPCl_3%7D%29%28p_%7BCl_2%7D%29%7D)
Now put all the values in this expression, we get :
![K_p=\frac{(10.24)}{(0.348)(0.441)}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%2810.24%29%7D%7B%280.348%29%280.441%29%7D)
![K_p=66.7](https://tex.z-dn.net/?f=K_p%3D66.7)
Therefore, the value of
at this temperature is 66.7
Among the choices, bromine exists as liquid under standard temperature and pressure conditions. Unlike other diatomic molecules which exist as gases, due to its heavy molecular weight, it exists as solid. Francium and cesium are solids while iodine is gas.Answer is 1.
Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
Answer:
Type of hybridisation
Explanation:
For example , saturated hydrocarbons have sp3 hybridisation while unsaturated hydrocarbons have either sp2 or sp hybridisation.
Example: Ethane( C2H6) has sp3 hybridisation and ethene(C2H4) has sp2 hybridisation and Ethyne(C2H2) has sp hybridization.
