Put the list in chronological order (1–5).
Leokris [45]

Explanation:

Filtration is a separation technique in which solid particles suspended in liquid medium are separated by allowing the mixture through the pores of the filter paper. By this solid particles get collect on filter paper and liquid drains out from the pores of the filter paper.

The chronological order for given steps will be:

  1. Weigh and fold the filter paper.
  2. Place the filter paper in the funnel, then place the funnel in the Erlenmeyer flask.
  3. Allow the solid/liquid mixture to drain through the filter.
  4. Use water to rinse the filter paper containing the mixture.
  5. Weigh the dried filter paper and copper.

F a shell can hold a maximum of 32 electrons, what is the value of n? 2 3 4 5
Arte-miy333 [17]

Answer: 4

Explanation:

Principle Quantum Numbers: This quantum number describes the size of the orbital. It is represented by n.

Azimuthal Quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number: This quantum number describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from (-l\text{ to }+l). When l = 2, the value of m_l will be -2, -1, 0, +1, +2.

Given : a f subshell, thus l = 3 , Thus the subshells present would be 3, 2, 1, 0 and thus n will have a value of 4.

Also electrons give are 32.

The formula for number of electrons is 2n^2.

2n^2=32

n=4

Thus principal quantum no will be n= 4.
