1031.9 K is the the kelvin temperature required for 0.0140 mol of gas to fill a balloon to 1.20L under 0.988 atm a pressure.
Explanation:
Data given:
number of moles of the gas = 0.0140
volume of the balloon= 1.20 litres
pressure of the gas = 0.988 atm
Kelvin temperature =?
R = 0.08206 L.atm/mole K
Formula used of ideal gas Law:
PV = nRT
putting the values in the equation after rearranging it:
T =
=
T = 1031.9 K
In the equation when the pressure is in atm, volume in litres, Gas constant has a value of 0.08206 L.atm/mole K and number of moles as moles the temperature unit is in Kelvin.
Answer:
Molecular Polarity. A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule
Explanation:
The correct answer to this question is A
Answer : The correct option is, solution deviate positively from.
Explanation:
According to the Rouault's law, there are two types of deviation which are negative deviation and positive deviation.
In negative deviation, the A-A interactions and B-B interactions are weaker than the A-B interactions that means A-B interactions are more due hydrogen bonding.
For example : chloroform & acetone form a non-ideal solution. The volume of solution will always be more.
In positive deviation, the A-A interactions and B-B interactions are stronger than the A-B interactions.
For example : acetone & benzene form a non-ideal solution. The volume of solution will always be less.
As per question, the interaction between individual liquids are stronger than the solution of two liquid's interactions. That means, the solution deviate positively from.
Hence, the correct option is, solution deviate positively from.
