During the winter months, many locations experience snow and ice storms. It is a common practice to treat roadways and sidewalks

with salt, such as NaCl . If a 11.3 kg bag of NaCl is used to treat the sidewalk, how many moles of NaCl does this bag contain

Answer:The moles of NaCL in the 11.3kg bag  is   193.36moles

Explanation:

Given that  a bag of NaCl = 11.3kg

1kg = 1000g

therefore 11.3 kg = 11,300g

Remember that

No of moles = mass of subatance/ molar mass of substance

The molar mass of NaCl = Na + Cl= 22.989769  + 35.453 =58.442769≈ 58.44g/mol

No of moles = mass of subatance/ molar mass of substance

                    = 11300g/ 58.44g/mol  =  193.36 moles

The moles of NaCL in the 11.3kg bag  is   193.36 moles.

Which of the following atoms has the greatest atomic radius? Oxygen (o) fluorine (F) Chlorine (CL) Carbon (C)
Andrei [34K]

Periodic Trend:

The Atomic radius of atoms generally decreases from left to right across a period

Group Trend:

The atomic radius of atoms generally increases from top to bottom within a group. As atomic number increases down a group, there is a increase in the positive nuclear charge, however the co-occurring increase in the number of orbitals wins out, increasing the atomic radius down a group in the periodic table

Answer :

The Atom with the greatest atomic radius is chlorine. Fluorine can be ruled out because it is in the same period as oxygen and further to the right down the period. Chlorine has the largest atomic size because it is farthest down the group of any of the above elements listed.

How does the size of a nanoparticle compare with the size of an atom?
RSB [31]
A nanoparticle is larger than an atom. A nanoparticle is usually made from a few hundred atoms. These  particles range from 1 nanometers to 100 nanometers. On the other hand an atom ranges from 0.1 nanometers to 105 nanometers. Using the sizes above, one can clearly see and understand that an atom is smaller.
