Thallium has got 81 protons
<u>Have a nice days.......</u>
Answer:
The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
Explanation:
This is a postulate of the Kinetic Molecular Theory.
A is wrong. KMT assumes the that the volume of the particles is negligible.
B is wrong. KMT assumes that the distance between the particles is muck greater than their size.
D is wrong. It takes the large distances as a fact. KMT uses this as an assumption.
Answer: , 4 molecules of ammonia, NH3(g) is produced; 2 molecules of ammonia, NH3(g) is produced respectively
Explanation:
The balanced equation is stated below N2(g) + 3H2(g) → 2NH3(g)
1 mole of N2(g) reacts with 3 moles of H2(g) to yield 2 moles of NH3(g)
1) If 2 molecules of N2 react, then the balanced equation will be
2N2(g) + 6H2(g) → 4NH3(g)
Thus, 4 molecules of ammonia, NH3(g) is produced
2) If 3 molecules of H2 react, then the balanced equation will be
N2(g) + 3H2(g) → 2NH3(g)
Thus, 2 molecules of ammonia, NH3(g) is produced
They can be stopped by a piece of paper.
