One of the properties is
Polylactic acid
The answer is (3) 11.2 L of N2(g). When the choices are all gases, the number of molecules depends on the molar number of the gas. Under the condition of STP, the molar number of a gas is depends on volume only. So the same volume of gas has the same number of molecules.
I am a little slow i cannot help with these that why i got this app lol
Answer:
BY increasing pressure and decreasing temperature.
Explanation:
- The solubility of a gas increases with decrease in the temperature.
- Also the solubility of a gas increases with increasing pressure.
- A gas can be compressed by increasing the pressure and decreasing the temperature.
- FOR example the gas in domestic LPG cylinders are in compressed form inside the cylinder.
- A gas takes the form of a liquid after compressing. Whenever it comes back to normal temperature and pressure it takes back to its gaseous form back.
The gaseous oxygen is water soluble and does not react with it
O2 + 2H2O + 4 e= 4 OH-
At 50 degrees Celsius and standard pressure inter-molecular forces of attraction are strongest in a sample of ethanoic acid.
Ethanoic acid has hydrogen atom bonded with a more electronegative atom; Oxygen. As a result, the molecule possesses strong intermolecular Hydrogen Bonds. Therefore; ethanoic acid, and all other carboxyllic acids have the tendency to form dimers.
