Answer:
V₂ = 2.64 mL
Explanation:
Given data:
Initial volume = 20 mL
Initial pressure = 1 atm
Initial temperature = 10°C (10 +273 = 283 K)
Final temperature = 100°C (100+273 = 373 K)
Final volume = ?
Final pressure = 10 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 1 atm. 20 mL . 373 K / 283 K. 10 atm
V₂ = 7460 mL.K.atm / 2830 K.atm
V₂ = 2.64 mL
Basically, this problem tells you to convert micrometers (μm) to millimeters (mm). The prefixes are used as hints for their values. Micrometer is 10⁻⁶ of a meter, while millimeter is 10⁻³ of a meter. If you use dimensional analysis,
(1.430×10⁻³ μm)*(10⁻⁶ m/1 μm)*(1 mm/10⁻³ m) = 1.43×10⁻⁶ mm
Answer: has greater impact on the freezing point depression of ice.
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor
= freezing point constant
m= molality
a) i = 4 for as it dissociates to give 4 ions in water.
b) i = 3 for as it dissociates to give 3 ions in water.
As the vant hoff factor is higher for , it has greater impact on the freezing point depression of ice.
Answer:
3p⁶ 4s² 3d²
Explanation:
From the question given above,
The electronic configuration of the element ends with 3p².
Another element having 8 more electrons will have the following electronic configuration as illustrated below:
Step 1:
Complete the 3p orbital by adding 4 electrons:
3p² + 4 electrons = 3p⁶
Step 2:
Fill the 4s orbital. This is so because 4s has a lower energy level compared to 3d.
4s²
Step 3:
Fill the 3d orbital with the remaining electrons i.e 2
3d²
Summary:
The continuation of the electronic configuration of the element with 8 more electrons is:
3p⁶ 4s² 3d²
The answers for the following questions are given below
- the advantage in operating the lifts in this manner is: (B). It reduces the time taken to reach the required floor, as the lifts can move faster.
- The most likely reason for this is: (A). Plants breathe very little during the winter months.
- Solution Q likely to do: (D). (Nothing can be said with just the given information.)
