As the gas is heated, the particles will begin to move faster. Likewise if you start to cool a gas, the particles will move slower. Because the gas remains at a constant pressure and volume, the particles cannot spread out so they simply move around the container even faster.
Hope this helps :)
Answer:
Rubidium
Explanation:
Rubidium is an alkali metal that has 37 protons 48 neutrons and 1 valence electron
A range of values is given for the density of gasoline and corn syrup could be because these substances changes their volumes along with the changes in temperature which will result to a change in density as well. Hope this answers the question.
Nitric acid does NOT react with water, water disassociates the molecules into those ions (above). ... Water,Being a polar solvent,…makes HNO3 ionise or dissociate or simply break down into Hydronium ions, i.e,H+ or H3O+ ions and nitrate NO3- ions..that's all.

Answer:
The molar concentration would have to be 0,81 M.
Explanation:
The osmotic pressure equation is:

where:
: osmotic pressure [atm]
M: molar concentration [M]
R: gas constant 0,08205 [atm.L/mol.°K]
T: absolute temperature [°K]
To solve the problem, we just clear M from the osmotic pressure equation and then replace our data using the appropiate units. Clearing the variable M we have:

We have to use temperature as absolute temperature (in kelvins), T=29+273=302 °K. Now we can replace our values in the equation:

As we can see, all units will be simplified and we'll have the molar concentration in mol/L.
