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.

This is true, " To increase acceleration of an object, you reduce its MASS or increase the applied force."
Given the mass of Titanium = 3.8 lb
Density of Titanium is 4.506 
We can calculate the volume of Titanium using density and mass.
Converting mass from lb to g:
Calculating the volume of Titanium using density and mass:
Converting volume from

Answer:
490 J.
Explanation:
The following data were obtained from the question:
Mass (m) = 5 Kg
Height (h) = 10 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (P.E) =..?
Potential energy is the energy stored in a body by virtue of its location. Mathematically, it can be expressed as:
P.E = mgh
Where:
m is the mass of the object measured in kilograms (Kg).
g is the acceleration due to gravity and the value is 9.8 m/s².
h is the height to which the object is located measured in metre (m)
P.E is the potential energy measured in joule (J).
With the above formula, we can obtain the potential energy possed by the object as follow:
P.E = mgh
P.E = 5 x 9.8 x 10
P.E = 490 J
The,the potential energy possed by the object is 490 J
