Answer:All the above
Explanation:
Non-ideal solutions are those solutions which do not obey Raoult's law in any conditions.
The molecular interactions of two components that is solute and solvent are different.
If there are two components A and B then the molecular interaction between A-A,B-B would be different from the molecular interactions in A-B .
The enthalpy of mixing and volume of mixing for non-ideal solutions have non zero values.
Enthalpy of mixing can be negative or positive in case of non-ideal solutions. If the enthalpy of mixing is negative so energy has been released upon mixing the two components and if enthalpy of mixing is positive then energy is absorbed upon mixing the two components.
Non-ideal solutions are simply those solutions which are not ideal hence they should not be having the characterstics of ideal solutions.
For ideal solutions the molecular interactions between the two components are equal.
So the molecular interaction between A-A,B-B would be equal to the molecular interaction between A-B. Also the enthalpy of mixing and volume of mixing for ideal solutions are zero hence all the statements provided here are correctly charactersing non-ideal solutions.
I beleive its A but not very sure though. If im wrong sorry. But if im right I hope it helps (:
Answer:
2:1 Hydrogen:Oxygen for all three answers.
Explanation:
Maltose has 22 hydrogen and 11 oxygen,
glucose and fructose both have 12 hydrogen and 6 oxygen, and water has 2 hydrogen and 1 oxygen.
Answer: 996 mmHg
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number 
of particles.
According to the ideal gas equation:
P = Pressure of the gas = ?
V= Volume of the gas = 25.5 L
T= Temperature of the gas = 13°C = (273+13) K = 286K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 1.42
(760mmHg=1atm)
Thus pressure of this gas sample is 996 mm Hg.
Answer:
Propane and butane are pure substances, which means that each one of them is made of only one type of molecule—propane molecules or butane molecules. In contrast, gasoline, diesel, and kerosene are not pure substances; they are mixtures of more than one substance.
