Explanation:
The reaction between magnesium and hydrochloric
acid combine to form a salt of magnesium chloride and release hydrogen
gas. This single replacement reaction is a classic example of a metal
reacting in an acid to release hydrogen gas.
Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.
<h3>Difference between Divergent and convergent boundaries </h3>
Divergent boundaries are the regions where new crust is formed when the plates pull away from each other while on the other hand, Convergent boundaries are the regions where crust is destroyed when one plate dives over another.
So we can conclude that Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

The mass of pentane the student should weigh out is
The density of pentane is 0.626 gcm-3
To calculate the mass of pentane following expression is used,
(Density is defined as the mass divide by volume)
Density = mass / volume
mass of pentane = Density of pentane * Volume of pentane
mass of pentane = 0.626 gcm-3 * 45.0 mL
= 28.17 g
Here the unit of mass of pentane is g,
However the unit of density is gcm-3 and unit of volume is mL i.e. cm3
Hence, Mass = gcm-3 * cm3
Mass = g
The mass of pentane the student should weigh out is 28.17g

Answer:
The Sun and the planets were born from a cloud of gas and dust called the solar nebula 4.6 billion years ago. The collapse of the solar nebula was most likely triggered by a shock wave from a nearby supernova explosion. The Sun formed in the center, with the planets surrounding it in a thin disk.
