Answer:
It would limit the amount of light absorbed by the plant and decrease the amount of food the plant is able to produce for itself.
Explanation:
Answer:
The molar heat of vaporization of dichloromethane is 30.8kJ/mole
Explanation:
Using Clausius Clapeyron equation
ln (P1/P2) = (ΔHvap/R) (1/T2-1/T1)
At initial temperature of Ooc , the vapour pressure is 134mmHg
Therefore T1 = 0+273 =273K
And P1 = 134mmHg
At normal boiling point of 40oC , the vapour pressure is 760mmhg
T2 = 40 +273 = 313K
P2 = 760mmHg
ln (134/760) = ΔHvap/(8.3145 J/molK)
( 1/313K - 1/273K)
ΔHvap = 30800J/mol
= 30.8kJ/mol
Therefore, the molar heat of vaporization can be calculated using
Clausius Clapeyron equation using the above steps
False.....................................
Answer:
1. Density of the rectangular prism is <u>20 g/cm3</u>
2. A material's ability to dissolve : <u>Soubility</u>
3. <u>Intensive property</u> : A physical property that is independent of sample size.
Explanation:
Volume of Prism is calculated by :
Length = 3 cm
Width = 2 cm
Height = 1 cm
V = 6 cm3
mass = 120 g
Density = 20 g/cm3
2.
<u>Solubility :</u>
- It is the chemical property of the substance.
- It shows the ability of the solute to dissolve in the solvent at a given temperature.
3.
<u>Intensive Properties:</u>
- These are bulk properties(Do not depend upon the amount of matter present)
- They are independent of sample size.
- Example : boiling point,melting point,temperature,refractive index
Respiration and Photosynthesis is different form each other because photosynthesis removes CO2 while respiration puts back CO2
I hoped this helped!
