To determine strength of attractive forces between the molecules the size of the molecules, their polarity (dipole moment), and their shape. ... If two molecules have about the same size and similar shape, the dipole-dipole intermolecular attractive force increases with increasing polarity.
I believe it’s true when particles move they create heat
Answer:
Exothermic Reaction
Explanation:
Its a combustion reaction and they are always exothermic in nature.
Answer: hydrogen is the limiting reactant.
Explanation:
We have the equation
.
This means that for every mole of nitrogen consumed, 3 moles of hydrogen are consumed.
- Considering the nitrogen, the reaction can occur 0.50 times.
- Considering the hydrogen, the reaction can occur 1.8/3 = 0.6 times.
Therefore, <u>hydrogen</u> is the limiting reactant.
