Answer:
a) At a given temperature, C₂H₆ has a higher vapor pressure than C₄H₁₀.
Explanation:
<em>Which statement below is true?
</em>
<em>a) At a given temperature, C₂H₆ has a higher vapor pressure than C₄H₁₀. </em>TRUE. C₂H₆ has a lower molar mass than C₄H₁₀ and a higher vapor pressure at most temperatures.
<em>b) The strongest intermolecular attractive forces present in liquid CCl₄ are dipole-dipole forces.</em> FALSE. CCl₄ is nonpolar, so the strongest intermolecular forces are dispersion forces.
<em>c) HCl has a higher boiling point than LiCl.</em> FALSE. LiCl (ionic compound) has a higher boiling point than HCl (covalent compound).
<em>d) H₂O has a greater polarizability than H₂Se.</em> FALSE. Se has a larger atomic radius than O which is why H₂Se has a greater polarizability than H₂O.
<em>e) In general, the stronger the intermolecular attractive forces, the lower the ∆Hºvap.</em> FALSE. In general, the stronger the intermolecular attractive forces, the higher the ∆Hºvap.
The answer would be letter A
Answer:
C released to the environment
Explanation:
I just did it in class
Answer:
The answer to your question is 2 molecules
Explanation:
Unbalanced chemical reaction
H₂(g) + N₂(g) ⇒ NH₃ (g)
Reactants Elements Products
2 H 3
2 N 1
Balanced chemical reaction
3H₂(g) + N₂(g) ⇒ 2NH₃ (g)
Reactants Elements Products
6 H 6
2 N 2
From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.
Explanation:
The absolute temperature is the lowest possible temperature in the universe. At this temperature, all atoms become motionless and cease to move.
The value of the absolute zero is pegged at -273.16°C.
- It is the lowest limit of the coldness of a body.
- Nothing can be colder than a body at absolute temperature.
- Many researches are underway to take advantage of this temperature value for scientific purpose.
- Thermodynamically, all process stops at this temperature.
- When a body is brought close a body at absolute zero, it can suffer cryogenic burn due to heat transfer.
