The envelope of gases surrounding the earth or another planet.
Answer:
The mass chloride is 2.903 grams
Explanation:
Step1: calculate the moles of FeCl3
moles = molarity x volume in liters
volume in liters = 100 ml /1000 = 0.1 L
molarity = 0.273 M = 0.273 mol / L
moles = 0.273 mol /L x 0.1 L = 0.0273 moles
step 2: find the moles of Cl
since there is 3 atoms of cl in FeCl3
= 3 x 0.0273 =0.0819 moles
Step 3: calculate mass of cl
mass= moles x molar mass
=0.0819 moles x 35.45 g/mol = 2.903 g
Amorphous and crystalline are the two types of matter classified by the arrangement of its atoms.
Explanation:
There are several criteria present to classify the matters present in this universe. We can classify the matter based on their physical state like solid, liquid and gas. We can also classify the matter based on their composition like pure substance and mixtures. Similarly another way of classifying the matter is based on their arrangement of atoms. If the atoms are arranged in an orderly manner, then they are termed as crystalline matter. And if the atoms are arranged in a random way, then they are termed as amorphous matter.
Thus, the two types of matter classified by the arrangement of its atoms are amorphous and crystalline.

Answer:
No, It is not okay to pretend on social media.
Explanation:
No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -
- This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses.
- Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights superficial desire of false popularity.
- It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.
