Answer:
A)16.3% (Hexane's formula is C6H14)
Because if the the technique is wrong the scientist is wrong I’m sorry it’s a bad answer :(
Answer:
See explanation
Explanation:
Matter may exist in three phases; solid, liquid and gas. The state in which matter exists depends on the extent of intermolecular forces operating in the substance.
In solid particles, the molecules that compose the solid are close together because the molecules of a solid do not move from place to place but they continue to vibrate about their fixed position.
For liquids, the molecules that compose a liquid are in random motion but are less energetic than molecules of a gas.
In gases, the molecules are not held together at all. The molecules of a gas have the highest degree of freedom. They move from one point another at a high velocity.
Hence, the order of increasing degree of movement of the particles in different states of matter = solids<liquids< gases.
Solids have well arranged particles, the molecules of a liquid are a little more disorderly than liquid particles while gas particles are the most disorderly of all the states of matter.
