Lab report for physical and chemical changes??!
slega [8]

Answer:

[See Below]

Explanation:

✦ Physical Changes:

  ✧ Is when the form changes, but not the chemicals in that form.

  ✧ An example of this would be chopping wood. It's still wood but it's a different size now. It's easier to burn it since it's smaller.

✦ Chemical Changes:

  ✧ Is when the chemicals inside that form change to something else entirely

  ✧ An example would be an egg, when you cook the egg it can turn into being scrambled or fried. But you can't eat the raw egg until the chemicals change.

What is the density of ammonia (NH3) at 293 K and 0.913 atm?
Anastaziya [24]

Answer:  The density of  Ammonia is 0.648 g/l

Explanation:

Density = Mass/ Volume

Mass of one mole of  Ammonia (NH3) = 17.031g

Volume =?

Using the ideal gas law we can determine the volume.

PV = nRT

P = 0.913 atm, V= ?, n = 1, R = 0.08206 L.atm/K, and T= 293K

Make V the subject of the formular, we then have;

V= nRT/ P = 1 mol x 0.08206 L.atm/ K.mol x 293 / 0.913 atm

               V = 24.04358/ 0.913 = 26.3L

Having gotten the value of Volume in this question, we then go back to solve for density.

Density = Mass/ Volume

                17.031g/ 26.3L = 0.64756 ≈ 0.648 g/l
