There are a total of 40 valence electrons in the PCl5 Lewis structure. Remember when you draw the Lewis structure for PCl5 that Phosphorous (P) is in Period 3 on the Periodic table. This means that it can hold more than 8 valence electrons.
I hope this helps and please don't report
If the graph has no trend which means almost constant, it indicates that the dependent variables will not change when the independent variables change.
Answer:
C.) 3.5 atm
Explanation:
Because you are dealing with pressure and volume, you can use Boyle's Law to help you find the missing variable. The general formula looks like this:
P₁V₁ = P₂V₂
In this formula, "P₁" and "V₁" represent the pressure and volume of the chamber originally. "P₂" and "V₂" represent the final pressure and volume. You have been given the values of all the other variables but "P₂". Therefore, you can plug these values into the formula and simplify to find the final pressure.
P₁ = 1.5 atm
V₁ = 1.4 L
P₂ = ?
V₂ = 0.60 L
P₁V₁ = P₂V₂ <---- Boyle's Law formula
(1.5 atm)(1.4 L) = P₂(0.60 L) <---- Plug in values
2.1 = P₂(0.60 L) <---- Multiply 1.5 and 1.4
3.5 = P₂ <----- Divide both sides by 0.60
Answer: The new volume of the balloon is 33 liters while T2 is 301K
Explanation:
Initial volume of helium V1 = 31 liters
Initial temperature T1 = 9°C
Convert temperature in Celsius to Kelvin
( 9°C + 273°C = 280K)
Final temperature T2 = 28°C
( 28°C + 273°C = 301K)
Final volume V2 = ?
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2
31/280 = V2/301
To get the value of V2, cross multiply
V2 = (31 x 301) / 280
V2 = 9331 / 280
V2 = 33.325 liters (approximated to 33liters)
Thus, the new volume of the balloon is 33 liters while T2 is 301K
