Answer:
Densities
Explanation:
A planet is a body which orbits the Sun (or father's it's sun) directly and is massive enough to show a hydrostatic equilibrium ( a spheroid) and be resilient in dominating its orbit
What comes to mind as we mention the word planet is specifically, the eight major bodies of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Note that Pluto once was considered a planet from the 17th century until 2006 and has now been reclassified as a dwarf planet.
Density is the measure with ratio of one quantity to another quantity.
It can quantitatively be a measure of the mass of matter contained by a unit volume.
The knowledge of density of gases comes in handy to calculate the relative amount of substances.
Answer:
Sublimation is a phase transition that occurs when a solid changes into a gas — or, as

Answer:
See detailed mechanism in the image attached
Explanation:
The mechanism shown in detail below is the synthesis of serine in steps.
The first step is the attack of the ethoxide ion base on the diethyl acetamidomalonate substrate giving the enolate and formaldehyde.
The second step is the protonation of the oxyanion from (1) above to form an alcohol as shown.
Acid hydrolysis of the alcohol formed in (3) above yields a tetrahedral intermediate, a dicarboxyamino alcohol.
Decarboxylation of this dicarboxyamino alcohol yields serine, the final product as shown in the image attached.

Answer:
atoms
Explanation:
Given that,
Given mass = 13200 g
Molar mass of potassium = 39.0983 g/mol
Let there are n number of moles. It is equal to mass divided by molar mass. It is equal to :
Let there are x atoms in 13200 g of potassium (k). It can be calculated :
So, there are atoms.
