Answer:
5.79 × 10^23 Oxygen atoms
Explanation:
Number of Oxygen atom in the compound = 4×3 = 12
Molar mass of Al2(SO4)3 = 342 g/mol.
No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole
2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen
= 5.79×10^23 Oxygen atoms
Half-life is the time required for the amount of something to fall to half its initial value. This term is usually used in nuclear physics to describe how quickly unstable atoms undergo decay, or how long stable atoms survive, radioactive decay, and it is also used more generally of any type of exponential or non-exponential decay.
In simpler terms: this is when an isotopes radioactivity is cut in half

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.
