Answer:
Planet: The object orbits the sun
Not planet: The object is a satellite
Planet: The regions surrounding the object are free from debris
Not Planet: The object is triangular in shape.
Explanation:
A planet is characterized as:
Spheroidal (or at least big enough to be round-ish)
It should orbit the sun (not other planets, so satellites like the moon is not considered as a planet)
It should have no debris, or cleared of debris around its orbit
Although there is now the dwarf planet category, it satisfies almost all charateristics to be considered a planet, except the cleared of debris part.
Answer:
Planet: The object orbits the sun
Not planet: The object is a satellite
Planet: The regions surrounding the object are free from debris
Not Planet: The object is triangular in shape.
Answer:
Chemical Formula: AlCl₃
Chemical Name: Aluminium Chloride
Properties are given below.
Explanation:
Chemical Formula:
Chemical formula depicts the total number of elemants forming a particular compound. It is common that all compounds are neutral in nature despite of the internal charges they contain. As given Aluminium has a + 3 charge while Chlorine has a -1 charge, therefore, to make a neutral compound we will require 3 Cl⁻ ions to neutralize one Al³⁺ ion hence, the chemical formula will be AlCl₃.
Chemical Name:
According to rules ionic compounds are named by naming the positive part first followed by negative part. In this case Al³⁺ being is name d first followed by Cl⁻ (remember the -ine in anions is replaced by -ide) hence, this compound will be name as Aluminium Chloride.
Properties:
Few physical and chemical properties of AlCl₃ are;
(i) It melts at 192.4 °C
(ii) Highly Soluble in water
(iii) It has a density of 2.48 g/cm³
(iv) Poor conductor of electricity
(v) It is used as catalyst in many organic reactions
(vi) Reacts with silver nitrate to form silver chloride and Aluminium Nitrate
