Answer:
Zinc + Hydrochloric Acid Zinc Chloride and Hydrogen Gas
Zn + 2HCI - ZnCl2 + H2
Explanation:
Be sure to label your model to clearly show how you are representing the atoms
It’s the first one: A. the water molecules stay the same they just change phase to a gas
Body waves travel through the interior of the Earth. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. the surface of the Earth).
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
P-waves are compression waves. They can propagate in solid or liquid material.
S-waves are shear waves. They only propagate in solid material.
By studying the trajectories of S-waves, scientists could prove that the Earth had a liquid outer core.
Answer:
Isopropanol>dichloromethane>1-butene>propane
Explanation:
Stronger intermolecular forces usually correlate with higher boiling points
Boiling points generally increases with molecular weight due to increased strength of dispersion forces
Hydrocarbons exhibit only dispersion forces.
For the arrangement of compounds above, isopropanol has the highest boiling point because it forms hydrogen bonds with water. Dichloromethane possess dipole-dipole interaction which accounts for its higher boiling point. 1-butene has a higher boiling point than propane because it has higher molecular mass thus greater dispersion forces.
