Describe the type of force which exists between particles in an ideal gas. A) There are strong attractive and repulsive forces between gas particles.
B) There are no attractive or repulsive forces between gas particles.
C) There are only attractive forces between gas particles.
D) There are only repulsive forces between gas particles.

B) There are no attractive or repulsive forces between gas particle

Explanation: According to the kinetic Molecular theory of ideal gases, There are no inter molecular  forces ( attraction or repulsion ) between gas particles  of an ideal gas because it is assumed that ideal gases are constantly in random motion with each particles moving  independently of the motion of other particles which bounce off each other upon collision.

Deviations to this assumptions occur at low pressures and high temperatures where ideal gases behave like real gases and exhibit  forces of attraction between particles, a reason for gases condensing to liquids.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

that's what i got you can count the number of atoms
